[pymvpa] RSA/RDM cross-validated mahalanobis

[Matteo Visconti di Oleggio Castello]

Hi Basile,

the new release of PyMVPA 2.6.1 introduces mvpa2.measures.rsa.CDist, that
allows you to compute cross-validated RSA (
https://github.com/PyMVPA/PyMVPA/blob/master/mvpa2/measures/rsa.py#L27),
and you can specify which distance metric you want to use, with additional
kwargs.
