mrg_dfsu_alter_time

 Modfies the selected DFSU file so that it begins at starttime and ends at
 endtime, with equally space timesteps inbetween

 INPUT
   starttime   A MATLAB datetime vector
   endtime     A MATLAB datetime vector

 OUTPUT
   NO OUTPUT AT CONSOLE. 
   Modifies the timestep information of the selected DFSU file.
