Explicit signature for NDFrame.to_hdf

[TomAugspurger]

Currently we have to_hdf(self, path_or_buf, key, **kwargs)

It'd be good to replace that with the actual signature (unless I'm missing a reason for the current implementation) and document it fully.

I would love to help. How can I get started on this?

Great! General contributing guidelines are at http://pandas-docs.github.io/pandas-docs-travis/contributing.html

For this specific one, I would look at to_hdf in pandas/pandas/io/pytables.py. Anywhere we pass kwargs currently (store.append and store.put) we'll need to figure out the correct set of keyword arguments expected. Some like mode, format, etc. will be straightforward. Others will take some digging. Let us know if you get stuck.

Cool. On it now.
