-	- add support for a few more frequency conversions that are missing

-	- support "secondly" frequency data in a more robust way. Frequency

-	- support for wider variety of standard numpy/ma functions

 	- add time series specific concepts/functions like moving averages, MACD, moving

-	- add support for more frequencies: semi-annual, hourly, minutely,

-	- Decide how best to handle frequency conversion between frequencies that
