[pymvpa] searchlight demo clarification

[Mark Eckert]

It looks like we have a software dependency issue that will take a little
time to sort out.  In the mean time, maybe we can discuss the figure you
sent.  Am I correct in interpretting that the color scale in the image
reflects the percent of correct classification for each voxel?  Other than
presenting a basic example of how the data can be represented, is this
example designed to emphasize a particular point (e.g., significance of
searchlight radius).

Thanks,
Mark
