New function "init_notebook_mode"

[mwouts]

This PR introduces a new function "init_notebook_mode" that

• loads the datatables.net library
• and overrides the html representation of the Pandas DataFrame and Series if desired (optional argument all_interactive).

This will hopefully solve #6 and #17.

Give it a try on Binder: https://mybinder.org/v2/gh/mwouts/itables/version_0.3.0?filepath=README.md. Now when we reload the notebook, the outputs disappear (because that is a text only notebook), but when the cells are re-executed the tables appear again (still, the cell with the init_notebook_mode needs to be executed first, otherwise the other cells won't work).

You can also try it locally with

pip install git+https://github.com/mwouts/itables.git@version_0.3.0

Hi @neon-ninja , @GZR5876 , @jpbarrette, I have prepared this PR which seems to solve #6 and #17.

But it changes how the fully interactive mode is initialized.

Now instead of doing

import itables.interactive

the user will have to do:

from itables import init_notebook_mode
init_notebook_mode(all_interactive=True)

Are you OK with this? And with the name of the function / the arguments?

Note that import itables.interactive will still work, but will issue a deprecation warning asking the user to use the new form.

I'll be glad to have your feedback. You can test it either locally or on binder (instructions & links in the previous comment).
