dot-appendDateFeatures function

Appends date features to data frame

Appends date features to data frame. Creates new column 'date' based on var if date is not already in the data frame. The newly created (or existing) date column is truncated to day. Columns for year, day of year (doy), decimal year (dyear), and month are added based on date. This function relies on smwrBase::baseDay and smwrBase::baseDay2decimal for doy and decimal year.

The baseDay and baseDay2decimal functions have been added to this package from smwrBase package.
