Right-align Markdown

[hugovk]

Simply adding a colon will align columns nicely in Markdown.

Builds on #23 by including a unit test for this change (eg.). This makes things much easier to develop without going over your quota!

Thanks!

I don't want the right-align; it's too Markdown-centric imo. Also, please use pytest instead of unittest.

[hugovk]

Would it be okay to add a command-line parameter for the right-align? It'd be very useful for me.

I'll add pytest.

Do you mean something like this:

from pypinfo import core

def test_tabulate():
    ...
    assert tabulated == expected

Or just having it as the pytest command for discovery?

[ofek]

Test looks good. A flag is fine.
