pandas logo has a latex typo

[jseabold]

Someone pointed this out on twitter (sorry, forgot who), but it you should be y_{it} = not y_it as it looks like it might be now. The t should also be subscript.

I just put up a gist with the matplotlib script I used to create the (new) logo, with the corrected LaTeX expression:

If you have a good suggestion about where in the pandas tree this should live permanently, I can make a PR with this stuff.

thanks @mdboom why don't you do a PR with this in pandas/doc/logo (new dir). If you can put the generated logo there as well. thanks.
