Months support doesn't seem to work

[martinb3]

Hello! Based on #7 and the PR #10 from @duramato, I expected to be able to use an expression like "1 month" using the current HEAD, but that doesn't seem to actually work:

$  mkvirtualenv foo
$ workon foo
$ pip install -e -e git://github.com/wroberts
$ pip install -e git://github.com/wroberts/pytimeparse.git@cc0550d3f4ec72d745ef2387603005ab52aa9538#egg=pytimeparse

Have you uncommented the references to months in the code?

@duramato -- no, apparently I didn't catch that. I wasn't expecting that. Maybe this should be in a branch so it's at least able to be pip install'd?

[duramato]

When I added it, did it commented per @wroberts "wish", since months/years are relative times to the calendar, more info #7 (comment).
To make it a branch sounds like a good idea, what you think @wroberts . Or maybe include it in the main branch.
