 * NOTE: Data Types
 *   Various basic data types are predefined for convenience sake and used
 *   constantly thoughout the entire toolkit. The developers are strongly
 *   encouraged to use these data types rather than built-in data types
 *   supported by compilers. 
 *
 * NOTE: Availabilty 
 *   Some of the data types may or may not be available depending on
 *   the capability of the compiler.
 *
 * GROUP: State Types
