Title: Created Exponential Smoothning issue #512

https://github.com/statsmodels/statsmodels/issues/512

This file has a basic Holts Winter Exponential smoothing and Brown simple exponential smoothing. It still needs a pandas wrapper. Please improve the code. Another thing is the additive model for Holt Winters still needs an if statement to fix the seasonal component.
