Support of nipy/nipype

[dvenum]

Good day.

I have merged nipy/nipype and your lts5/cmp_nipype.
This finish connection matrix for test data, but there is a ugly code in parcellation.py because you moved code from nipype to cmp2.0. I resolve it via conditions: "if CMP_VERSION < 2:" now, but it not good.
So, may I bring cmtklib to old cmp?
