/**
+ * @class Ext.util.Format
+
+This class is a centralized place for formatting functions inside the library. It includes
+functions to format various different types of data, such as text, dates and numeric values.
+
+__Localization__
+This class contains several options for localization. These can be set once the library has loaded,
+all calls to the functions from that point will use the locale settings that were specified.
+Options include:
+- thousandSeparator
+- decimalSeparator
+- currenyPrecision
+- currencySign
+- currencyAtEnd
+This class also uses the default date format defined here: {@link Ext.date#defaultFormat}.
+
+__Using with renderers__
+There are two helper functions that return a new function that can be used in conjunction with
+grid renderers:
+
+ columns: [{
+ dataIndex: 'date',
+ renderer: Ext.util.Format.dateRenderer('Y-m-d')
+ }, {
+ dataIndex: 'time',
+ renderer: Ext.util.Format.numberRenderer('0.000')
+ }]
+
+Functions that only take a single argument can also be passed directly:
+ columns: [{
+ dataIndex: 'cost',
+ renderer: Ext.util.Format.usMoney
+ }, {
+ dataIndex: 'productCode',
+ renderer: Ext.util.Format.uppercase
+ }]
+
+__Using with XTemplates__
+XTemplates can also directly use Ext.util.Format functions:
+
+ new Ext.XTemplate([
+ 'Date: {startDate:date("Y-m-d")}',
+ 'Cost: {cost:usMoney}'
+ ]);
