 * This grammar introduces freely defined generic types

 * 
 * These generics are covering a wide range of uses for generic types,
 * although they don't cover type restrictions on the arguments, like in 
 * Java. 
 * 
 * This eases the reuse of type structures in languages similar to Java,
 * that are somewhat simplified.
 *
 * This grammar is part of a hierarchy of types, namely 
 * * types.MCBasicTypes.mc4       
 *   * types/MCArrayTypes.mc4
 *   * types/MCCollectionTypes.mc4
