DOC: document support for in-memory HDFStore

See original GitHub issue

It seems to be currently imposible to have an in-memory HDFStore.

Any of my attempts at using io.BytesIO failed.

This can be useful for applications where the bytes of the resulting HDF file need to be sent over the network.

Do you want the driver parameter to be explicitly mentioned? As it is catched by the **kwargs and passed on to tables.open_file method, it is not really a Pandas parameter.

I currently have added to the docstring that **kwargs passes its parameters to PyTables. Maybe this is too much but I also added an example using **kwargs, passing the driver paramter to create an in-memory HDFStore.

Furthermore, I have added HDFStore class to the reference api, as it was not autogenerated and also made **kwargs more clear that it passes its parameters to PyTables.

Added in the cookbook the method of creating in-memory HDFStores, including an example.
