Intervals

Intervals in vtools are equivalent to freq arguments in Pandas. In some cases strings or timeDelta objects can be used, but the one that behaves best in math operations and the main implementation class in Pandas is the Offset class.

One way to construct intervals quickly are the vtools.seconds() vtools.minutes() etc convenience functions.
