FIXME: Document this
Changes:
2003/04/02 Al Riddcoh alriddoch@zepler.org Add in some assignment operators for efficiency 2002/11/07 Al Riddcoh alriddoch@zepler.org Changed the name to Element as Object is a stupid name for a class. 2000/08/05 Karsten-O. Laux klaux@rhrk.uni-kl.de Changed the members to pointers which only get created when really needed. This is a major speedup for passing Object as parameter or when copying it. Because copying of unused members is omitted.
All pointers are stored as a union, so we save memory ! Changed IntType to long and added convinience Constructors for float, int and bool
