Lack of documentation

[buggsi]

There's no documentation or examples about any of the functions, can you write some?

I agree the docs can be improved - some examples would be very useful.

However at present pretty much every function in nntp.py has docstrings and there are sphinx generated docs at https://greenbender.github.io/pynntp/

I'll add a link to the docs from the top level README now, and look to add examples to the docs when I have some time.

Docs are now linked in README
