[pymvpa] _clf_internals question

[Per B. Sederberg]

Howdy Folks:

Just a quick note that I renamed them to GLMNET_C and GLMNET_R as per
Yarik's suggestion in the previous email.

I did not wrap 100% of the functionality of the R code, just what I
thought made sense for a first pass application to neural data, so let
me know if there's anything missing that would like me to add to the
wrapping code.

Best,
P
