Bug fixes and enhancements

Shortened time to read tables into R after downloading from CRU.

Fixed bug where values were reduced 10-fold.

Corrected incorrect comment sections.

create.stack now just uses the lon/lat values from any CRU CL2.0
dataset given to it. This is because the precipitation data has a 6
more cells than the temperature dataset.

The month names are now passed along into the create.stack() function
as they should be to name the raster layer objects.
