added ability to move outlet indicies to new grid in uhs2paramfile.py
Fixed bug in convert.py where indicies read from files were aparently 1 based (rather than 0 based)
Fixed bug in tar_inputs helper function so that the full path is not listed as the archive name when unzipped.
Updates to history file and time utility modules

History files now support RVICHIST_MFILT > 1.  This allows for multiple timesteps to be included in a single history file.  Saving time.
Time utility now distinguishes between keywords such as "ndays" and "nday".  The plural representing a continuing event (writing of restart file).
removed mask and scale option from read method.  This disallows the automatic conversion of netcdf array to numpy masked arrays.  A known choke point in model run time.
