[pymvpa] getting details for arguments

[Yaroslav Halchenko]

Thank you Felipe for helping out

indeed was our omission to not provide available choices within the
docstring.   It should get fixed soon:
https://github.com/PyMVPA/PyMVPA/pull/158

meanwhile, for such parameters, you could simply check those params
repr, and listed there choices:

*In [10]: mvpa2.clfs.gda.LDA().params
Out[10]: ParameterCollection(items=[Parameter(laplacian_smoothing, name='prior', doc='How to compute prior distribution.', allowedtype=basestring, choices=['laplacian_smoothing', 'uniform', 'ratio']), Parameter(False, name='retrainable', doc="Either to enable retraining for 'retrainable' classifier.", allowedtype=bool), Parameter(True, name='allow_pinv', doc='Allow pseudo-inverse in case of degenerate covariance(s).', allowedtype=bool)], name='params')
