+</span> * @class String
+ *
+ * `String` is a global object that may be used to construct String instances.
+ *
+ * String objects may be created by calling the constructor `new String()`. The `String` object wraps
+ * JavaScript's string primitive data type with the methods described below. The global function
+ * `String()` can also be called without new in front to create a primitive string. String literals in
+ * JavaScript are primitive strings.
+ *
+ * Because JavaScript automatically converts between string primitives and String objects, you can call
+ * any of the methods of the `String` object on a string primitive. JavaScript automatically converts the
+ * string primitive to a temporary `String` object, calls the method, then discards the temporary String
+ * object. For example, you can use the `String.length` property on a string primitive created from a
+ * string literal:
+ *
+ * s_obj = new String(s_prim = s_also_prim = "foo");
+ *
+ * s_obj.length; // 3
+ * s_prim.length; // 3
+ * s_also_prim.length; // 3
+ * 'foo'.length; // 3
+ * "foo".length; // 3
+ *
+ * (A string literal is denoted with single or double quotation marks.)
+ *
+ * String objects can be converted to primitive strings with the `valueOf` method.
+ *
+ * String primitives and String objects give different results when evaluated as JavaScript. Primitives
+ * are treated as source code; String objects are treated as a character sequence object. For example:
+ *
+ * s1 = "2 + 2"; // creates a string primitive
+ * s2 = new String("2 + 2"); // creates a String object
+ * eval(s1); // returns the number 4
+ * eval(s2); // returns the string "2 + 2"
+ * eval(s2.valueOf()); // returns the number 4
+ *
+ * # Character access
+ *
+ * There are two ways to access an individual character in a string. The first is the `charAt` method:
+ *
+ * return 'cat'.charAt(1); // returns "a"
+ *
+ * The other way is to treat the string as an array, where each index corresponds to an individual
+ * character:
+ *
+ * return 'cat'[1]; // returns "a"
+ *
+ * The second way (treating the string as an array) is not part of ECMAScript 3. It is a JavaScript and
+ * ECMAScript 5 feature.
+ *
+ * In both cases, attempting to set an individual character won't work. Trying to set a character
+ * through `charAt` results in an error, while trying to set a character via indexing does not throw an
+ * error, but the string itself is unchanged.
+ *
+ * # Comparing strings
+ *
+ * C developers have the `strcmp()` function for comparing strings. In JavaScript, you just use the less-
+ * than and greater-than operators:
+ *
+ * var a = "a";
+ * var b = "b";
+ * if (a < b) // true
+ * print(a + " is less than " + b);
+ * else if (a > b)
+ * print(a + " is greater than " + b);
+ * else
+ * print(a + " and " + b + " are equal.");
+ *
+ * A similar result can be achieved using the `localeCompare` method inherited by `String` instances.

+//Methods
+
+<span id='String-method-fromCharCode'>/**
+</span> * @method fromCharCode
+ * Returns a string created by using the specified sequence of Unicode values.
+ *
+ * This method returns a string and not a `String` object.
+ *
+ * Because `fromCharCode` is a static method of `String`, you always use it as `String.fromCharCode()`,
+ * rather than as a method of a `String` object you created.
+ *
+ * Although most common Unicode values can be represented in a fixed width system/with one number (as
+ * expected early on during JavaScript standardization) and `fromCharCode()` can be used to return a
+ * single character for the most common values (i.e., UCS-2 values which are the subset of UTF-16 with
+ * the most common characters), in order to deal with ALL legal Unicode values, `fromCharCode()` alone
+ * is inadequate. Since the higher code point characters use two (lower value) "surrogate" numbers to
+ * form a single character, `fromCharCode()` can be used to return such a pair and thus adequately
+ * represent these higher valued characters.
+ *
+ * Be aware, therefore, that the following utility function to grab the accurate character even for
+ * higher value code points, may be returning a value which is rendered as a single character, but
+ * which has a string count of two (though usually the count will be one).
+ *
+ * // String.fromCharCode() alone cannot get the character at such a high code point
+ * // The following, on the other hand, can return a 4-byte character as well as the
+ * // usual 2-byte ones (i.e., it can return a single character which actually has
+ * // a string length of 2 instead of 1!)
+ * alert(fixedFromCharCode(0x2F804)); // or 194564 in decimal
+ *
+ * function fixedFromCharCode (codePt) {
+ * if (codePt > 0xFFFF) {
+ * codePt -= 0x10000;
+ * return String.fromCharCode(0xD800 + (codePt >> 10), 0xDC00 +
+ * (codePt & 0x3FF));
+ * }
+ * else {
+ * return String.fromCharCode(codePt);
+ * }
+ * }
+ *
+ * The following example returns the string "ABC".
+ *

+//Properties
+
+<span id='String-property-length'>/**
+</span> * @property {Number} length
+ * Reflects the length of the string.
+ *
+ * This property returns the number of code units in the string. UTF-16, the string format used by JavaScript, uses a single 16-bit
+ * code unit to represent the most common characters, but needs to use two code units for less commonly-used characters, so it's
+ * possible for the value returned by `length` to not match the actual number of characters in the string.
+ *
+ * For an empty string, `length` is 0.
+ *
+ * var x = "Netscape";
+ * var empty = "";
+ *
+ * console.log("Netspace is " + x.length + " code units long");

+//Methods
+
+<span id='String-method-charAt'>/**
+</span> * @method charAt
+ * Returns the character at the specified index.
+ *
+ * Characters in a string are indexed from left to right. The index of the first character is 0, and
+ * the index of the last character in a string called `stringName` is `stringName.length - 1`. If the
+ * index you supply is out of range, JavaScript returns an empty string.
+ *
+ * The following example displays characters at different locations in the string "Brave new world":
+ *
+ * var anyString="Brave new world";
+ *
+ * document.writeln("The character at index 0 is '" + anyString.charAt(0) + "'");
+ * document.writeln("The character at index 1 is '" + anyString.charAt(1) + "'");

+ * document.writeln("The character at index 4 is '" + anyString.charAt(4) + "'");
+ * document.writeln("The character at index 999 is '" + anyString.charAt(999) + "'");
+ *
+ * These lines display the following:
+ *
+ * The character at index 0 is 'B'
+ * The character at index 1 is 'r'
+ * The character at index 2 is 'a'
+ * The character at index 3 is 'v'
+ * The character at index 4 is 'e'
+ * The character at index 999 is ''
+ *
+ * The following provides a means of ensuring that going through a string loop always provides a whole
+ * character, even if the string contains characters that are not in the Basic Multi-lingual Plane.
+ *

+ * for (var i=0, chr; i < str.length; i++) {
+ * if ((chr = getWholeChar(str, i)) === false) {continue;} // Adapt this line at the top of
+ * each loop, passing in the whole string and the current iteration and returning a variable to
+ * represent the individual character
+ * alert(chr);
+ * }
+ *
+ * function getWholeChar (str, i) {
+ * var code = str.charCodeAt(i);
+ *
+ * if (isNaN(code)) {

+ * have already processed
+ * }
+ *
+ * While the second example may be more frequently useful for those wishing to support non-BMP
+ * characters (since the above does not require the caller to know where any non-BMP character might
+ * appear), in the event that one _does_ wish, in choosing a character by index, to treat the surrogate
+ * pairs within a string as the single characters they represent, one can use the following:

+<span id='String-method-charCodeAt'>/**

+ * are used to comprise the real character. Because of this, in order to examine or reproduce the full

+ * `charCodeAt` returns `NaN` if the given index is not greater than 0 or is greater than the length of

+ *
+ * The following example defines two string variables. The variables contain the same string except that the second string contains
+ * uppercase letters. The first `writeln` method displays 19. But because the `indexOf` method is case sensitive, the string
+ * "cheddar" is not found in `myCapString`, so the second `writeln` method displays -1.

+</span> * @method replace
+ * Used to find a match between a regular expression and a string, and to replace the matched substring
+ * with a new substring.
+ *
+ * This method does not change the `String` object it is called on. It simply returns a new string.
+ *
+ * To perform a global search and replace, either include the `g` flag in the regular expression or if
+ * the first parameter is a string, include `g` in the flags parameter.
+ *
+ * The replacement string can include the following special replacement patterns:
+ *
+ * | Pattern | Inserts
+ * |:--------------|:--------------------------------------------------------------------------------------
+ * | `$$` | Inserts a `$`.
+ * | `$&` | Inserts the matched substring.
+ * | `$`` | Inserts the portion of the string that precedes the matched substring.
+ * | `$'` | Inserts the portion of the string that follows the matched substring.
+ * | `$n` or `$nn` | Where `n` or `nn` are decimal digits, inserts the _n_th parenthesized submatch string, provided the first
+ * | | argument was a `RegExp` object.
+ *
+ * You can specify a function as the second parameter. In this case, the function will be invoked after the match has been
+ * performed. The function's result (return value) will be used as the replacement string. (Note: the above-mentioned special
+ * replacement patterns do not apply in this case.) Note that the function will be invoked multiple times for each full match to be
+ * replaced if the regular expression in the first parameter is global.
+ *
+ * The arguments to the function are as follows:
+ *
+ * | Possible Name | Supplied Value
+ * |:--------------|:--------------------------------------------------------------------------------------
+ * | `str` | The matched substring. (Corresponds to `$&` above.)
+ * | `p1, p2, ...` | The _n_th parenthesized submatch string, provided the first argument to replace was a `RegExp` object.
+ * | | (Correspond to $1, $2, etc. above.)
+ * | `offset` | The offset of the matched substring within the total string being examined. (For example, if the total string
+ * | | was "`abcd`", and the matched substring was "`bc`", then this argument will be 1.)
+ * | `s` | The total string being examined.
+ *
+ * (The exact number of arguments will depend on whether the first argument was a `RegExp` object and, if so, how many parenthesized
+ * submatches it specifies.)
+ *
+ * The following example will set `newString` to "`XXzzzz - XX , zzzz`":
+ *
+ * function replacer(str, p1, p2, offset, s)
+ * {
+ * return str + " - " + p1 + " , " + p2;
+ * }
+ * var newString = "XXzzzz".replace(/(X*)(z*)/, replacer);
+ *
+ * In the following example, the regular expression includes the global and ignore case flags which permits replace to replace each
+ * occurrence of 'apples' in the string with 'oranges'.
+ *
+ * var re = /apples/gi;
+ * var str = "Apples are round, and apples are juicy.";
+ * var newstr = str.replace(re, "oranges");
+ * print(newstr);
+ *
+ * In this version, a string is used as the first parameter and the global and ignore case flags are specified in the flags
+ * parameter.
+ *
+ * var str = "Apples are round, and apples are juicy.";
+ * var newstr = str.replace("apples", "oranges", "gi");
+ * print(newstr);
+ *
+ * Both of these examples print "oranges are round, and oranges are juicy."
+ *
+ * In the following example, the regular expression is defined in replace and includes the ignore case flag.
+ *
+ * var str = "Twas the night before Xmas...";
+ * var newstr = str.replace(/xmas/i, "Christmas");
+ * print(newstr);
+ *
+ * This prints "Twas the night before Christmas..."
+ *
+ * The following script switches the words in the string. For the replacement text, the script uses the $1 and $2 replacement
+ * patterns.
+ *
+ * var re = /(\w+)\s(\w+)/;
+ * var str = "John Smith";
+ * var newstr = str.replace(re, "$2, $1");
+ * print(newstr);
+ *
+ * This prints "Smith, John".
+ *
+ * In this example, all occurrences of capital letters in the string are converted to lower case, and a hyphen is inserted just
+ * before the match location. The important thing here is that additional operations are needed on the matched item before it is
+ * given back as a replacement.
+ *
+ * The replacement function accepts the matched snippet as its parameter, and uses it to transform the case and concatenate the
+ * hyphen before returning.
+ *
+ * function styleHyphenFormat(propertyName)
+ * {
+ * function upperToHyphenLower(match)
+ * {
+ * return '-' + match.toLowerCase();
+ * }
+ * return propertyName.replace(/[A-Z]/, upperToHyphenLower);
+ * }
+ *
+ * Given `styleHyphenFormat('borderTop')`, this returns 'border-top'.
+ *
+ * Because we want to further transform the _result_ of the match before the final substitution is made, we must use a function.
+ * This forces the evaluation of the match prior to the `toLowerCase()` method. If we had tried to do this using the match without a
+ * function, the `toLowerCase()` would have no effect.
+ *
+ * var newString = propertyName.replace(/[A-Z]/, '-' + '$&'.toLowerCase()); // won't work
+ *
+ * This is because `'$&'.toLowerCase()` would be evaluated first as a string literal (resulting in the same `'$&'`) before using the
+ * characters as a pattern.
+ *
+ * The following example replaces a Fahrenheit degree with its equivalent Celsius degree. The Fahrenheit degree should be a number
+ * ending with F. The function returns the Celsius number ending with C. For example, if the input number is 212F, the function
+ * returns 100C. If the number is 0F, the function returns -17.77777777777778C.
+ *
+ * The regular expression `test` checks for any number that ends with F. The number of Fahrenheit degree is accessible to the
+ * function through its second parameter, `p1`. The function sets the Celsius number based on the Fahrenheit degree passed in a
+ * string to the `f2c` function. `f2c` then returns the Celsius number. This function approximates Perl's `s///e` flag.
+ *
+ * function f2c(x)
+ * {
+ * function convert(str, p1, offset, s)
+ * {
+ * return ((p1-32) * 5/9) + "C";
+ * }
+ * var s = String(x);
+ * var test = /(\d+(?:\.\d*)?)F\b/g;
+ * return s.replace(test, convert);
