 * NAME:        Geometry Library (C++)
 *
 * COMMENTS:
 *      This simply contains a list of token identifiers for primitive
 *      types.  Currently, there may be up to 32 types of primitives
 *      supported.  This may change (but not easily).  From the list
 *      below, it is apparent that this should be lots of primitives
 *      to work with.
 *
 *      Each primitive type must have a unique bit so that code can
 *      quickly search through the primitives it knows about.
