Document getting a time from parsedatetime into a standard Python structure

[dellis23]

It seems like most people will want some additional way to manipulate the information retrieved from parsedatetime. It would be nice to have a simple example of how they can do that.

For instance:

In [11]: from time import mktime

In [12]: from datetime import datetime

In [14]: datetime.fromtimestamp(mktime(parsedatetime.Calendar().parse('4:30')[0]))
Out[14]: datetime.datetime(2015, 8, 4, 4, 30)

Let me know if you think this is valuable and I can whip something up for the readme in a more concise / readable format.

I think this would be an excellent start to an examples or howto page/section
