[GEMPAK #CFB-418091]: case study usage for NMAP2/GARP applications

Paul,

If your case study file directory mirrors your current data directory (eg
hopefully Y2K 4 digit years ...some of those cases in the 90's will probably 
need
some file name tweaking), then to run a case study environment is just
a matter of creating a short script which sets the GEMDATA, MODEL, SAT, RAD
environmental variables for the shell  (and optionally then fires up ntl).
Do that after the user has already sourced Gemenviron so that
the new settings overwrite the data locations defined in Gemenviron, but
all the other GEMTBL, GEMEXE, GEMHLP etc variables remain from
the Gemenviron configuration.

The $GEMTBL/config/datatype.tbl file and $GARPHOME/config/Garp_defaults
files use the environmental variables above to make the data tree relative
so that your can just redefine the variables before launching the application
so that it looks doen the case study tree. Your Old Garp_defaults may
still be using the $HDS directory for model data (recall old garp
required all grid data to be placed in a single directory, but
as models have gotten bigger and some now even put each forecast hour in a 
separate file-
the mode current versions havd updated Garp to use the datatype.tbl template
file so that each model can be in a unique directory ie $MODEL/nam, $MODEL/gfs 
etc.).
