Experimental support for 2 and 3 using six

[benhosmer]

I do see what you mean now though with the node configure:

...
    INFO:virtual-node:b'      ^'
    INFO:virtual-node:b"SyntaxError: Missing parentheses in call to 'print'"
    CRITICAL:virtual-node:b'  File "./configure", line 319'
...

This was more an example of using six as a prototype solution.
