Removed Dictmixin from py2compat as collections.UserDict seems to be a good match, provided it is _init_'d
2to3 doesnt convert doctests properly, so just disable them for py3+
Created a new unittest replacing ALL of the code.py doctests
Completely passes test suite on py2.6,2.7
core.py doctest replacements and original unittests all pass under py3.2
