Feature request: integrate with prompt_toolkit

[infokiller]

The prompt_toolkit project is getting a lot of traction and was chosen for IPython 5.0.
It's written in pure, modern python so integrations should be relatively easy.

Is it possible to integrate with it?

@jonathanslenders what do you think?

Thanks!

This could be interesting! Personally, I don't have the resources to do the integration. But if there's anything missing into prompt_toolkit that would prevent a useful integration, I'd like to hear about that.

Thanks @jonathanslenders !
@ardagnir how difficult do you think it would be?

[ardagnir]

It shouldn't be too difficult. The main problem is that Athame is in C and prompt_toolkit is in python. The next step would probably be SWIG-wrapping Athame so that it can be called by other languages like python.

This is probably not worth the effort until #50 is done, but once that happens, Athame support for IPython would be pretty awesome.
