 * Enum Type Definition

 * kind of type, often integers.

 * Example:
 *
 *     $RGBType = newEnumType([
 *       'name'   => 'RGB',
 *       'values' => [
 *         'RED'   => ['value' => 0],

 *         'BLUE'  => ['value' => 2]
 *       ]
 *     ]);
 *
 * Note: If a value is not provided in a definition, the name of the enum value
 * will be used as its internal value.
