[pymvpa] effect size (in lieu of zscore)

[Yaroslav Halchenko]

before discussion kicks in -- out of curiosity... what happens if you
either do nested cross-validation to choose C parameter or just set it
a bit higher (e.g. C=-5 to still be scaled according  to the data), what
if you do zscoring across full time series (not just baseline condition)
-- for both of those there are explanations, I just wondered to get
better idea of what might be happening in your case
