Version 1.0

This version brings integration with pandas and is very close to the R version, in terms of present functionalities.

This version comes with the new function getbizdays that returns the amount of business day in a year or a month.

The integration with pandas makes it work pretty close with DatetimeIndex and Timestamp date types.

But unfortunately this is no longer compatible with python 2 and with the changes made some breaks might happen.

Chasing R

I've implemented a few differences in the DateIndex building process.
These changes were present in bizdays' R version.
Many new tests have been written to assert that both versions work the same way.

v0.2.0

Complete code review.
Many new functions, including the new Calendar.getdate which returns dates for date expressions and vectorized operations.
