  Natural, Integer, and Rational numbers
- added Value() methods to access small Natural and Integers
  as uint64 or int64 respectively, and to get the components
  of Rational numbers
- fixed a bug with Integer creation
- removed some _'s from names
- added more comments in places
- added test cases

* move duint8, duint16, duint32, duint64, duintptr into gc.
* tidy genwrapper.
