/**
+ * @class Ext.form.field.Base
+ * @extends Ext.Component
+
+Base class for form fields that provides default event handling, rendering, and other common functionality
+needed by all form field types. Utilizes the {@link Ext.form.field.Field} mixin for value handling and validation,
+and the {@link Ext.form.Labelable} mixin to provide label and error message display.
+
+In most cases you will want to use a subclass, such as {@link Ext.form.field.Text} or {@link Ext.form.field.Checkbox},
+rather than creating instances of this class directly. However if you are implementing a custom form field,
+using this as the parent class is recommended.
+
+__Values and Conversions__
+
+Because BaseField implements the Field mixin, it has a main value that can be initialized with the
+{@link #value} config and manipulated via the {@link #getValue} and {@link #setValue} methods. This main
+value can be one of many data types appropriate to the current field, for instance a {@link Ext.form.field.Date Date}
+field would use a JavaScript Date object as its value type. However, because the field is rendered as a HTML
+input, this value data type can not always be directly used in the rendered field.
+
+Therefore BaseField introduces the concept of a "raw value". This is the value of the rendered HTML input field,
+and is normally a String. The {@link #getRawValue} and {@link #setRawValue} methods can be used to directly
+work with the raw value, though it is recommended to use getValue and setValue in most cases.
+
+Conversion back and forth between the main value and the raw value is handled by the {@link #valueToRaw} and
+{@link #rawToValue} methods. If you are implementing a subclass that uses a non-String value data type, you
+should override these methods to handle the conversion.
+
+__Rendering__
+
+The content of the field body is defined by the {@link #fieldSubTpl} XTemplate, with its argument data
+created by the {@link #getSubTplData} method. Override this template and/or method to create custom
+field renderings.
