+/**
+ * This class will simulate LocalStorage on IE 7 and return the native version on modern browsers.
+ * Storage is done using userData on IE 7 and a special serialization format. The format is designed
+ * to be as small as possible by making sure that the keys and values doesn't need to be encoded. This
+ * makes it possible to store for example HTML data.
+ *
+ * Storage format for userData:
+ * <base 32 key length>,<key string>,<base 32 value length>,<value>,...
+ *
+ * For example this data key1=value1,key2=value2 would be:
+ * 4,key1,6,value1,4,key2,6,value2
+ *
+ * @class tinymce.util.LocalStorage
+ * @static
+ * @version 4.0
+ * @example
+ * tinymce.util.LocalStorage.setItem('key', 'value');
+ * var value = tinymce.util.LocalStorage.getItem('key');
