[pymvpa] Spatial Searchlight on Event-related datasets

[Swaroop Guntupalli]

Sounds good.
I tried this approach with Sphere with radius of number of events, but I
wasn't sure if it only uses all events forward in time from first event or
also goes back (which shouldn't happen for most cases anyway).

Thanks,
Swaroop
