* TEnumerable class.
* TEnumerable is the base class for all enumerable types.
* To define an enumerable type, extend TEnumberable and define string constants.
* Each constant represents an enumerable value.
* The constant name must be the same as the constant value.
* For example,
* <code>
* class TTextAlign extends \Prado\TEnumerable
* {
* const Left='Left';
* const Right='Right';
* }
* </code>
* Then, one can use the enumerable values such as TTextAlign::Left and
* TTextAlign::Right.
