addPolygon

Draw a polygon on an existing xts plot by specifying a time series of y 
coordinates. The xts index is used for the x coordinates and the first two 
columns are the upper and lower y coordinates, respectively.

Provide for uniform handling of R's different time-based data classes by extending zoo, maximizing native format information preservation and allowing for user level customization and extension, while simplifying cross-class interoperability.
