Rename the WRF function to something more apprpriate. Also fix the help to be correct.
Fix some of the cell arrays which are created when we are using the most recent model results (2010 onwards).
Add functionality to concatenate a number of files into series of 4D fields in a struct. This means that a time series of a 3D variable can be generated. Also add a helper function to get the proper time from the time variable (this is still not 100% working). Finally, add a TODO list of things to fix.
