ENH: Add Series.to_latex() and _repr_latex_

[TomAugspurger]

Could be as simple as as self.to_frame().to_latex(...). Or could move it to generic.py

This will help clean up logic in NDFrame._ipython_display_.

Here I am again to try contributing.

Is this done or does work need to be done here?

[TomAugspurger]

That's be great. The issue is open, and not one else has said they want to work on it, so go right ahead.

Let us know if you have any troubles.

@TomAugspurger I'll take a stab at this one during PyCon sprints. Thanks!
