documentation updates for utility programs

[cseppan]

Reported by Roger Kwok on the CMAS Forum:

For inlineto2d.f, the additional environment variables are

GRIDDESC for a grid description file; and
IOAPI_GRIDNAME_1 for a grid name from GRIDDESC

For mrgpt.f, renaming is needed for the follow environment variables, otherwise the ones in the manual are not recognized by the program.

Replace FILELIST_STACK with FILELIST_S;
replace FILELIST_INLN with FILELIST_E;
replace OUTFILE_STACK with OUTFILE_S; and
replace OUTFILE_INLN with OUTFILE_E.

Moreover, REPMRGGRID and REPMERG_ADJ are not found anywhere in the code. It seems to me that the following variables must be set instead, though optional:

CREATE_REPORT ! consent to create a report, admitting either Y or N
REPORT_BY_STATE ! for the output report file

---

There may be other utility programs where the documentation is out of date (especially IOAPI_GRIDNAME_1).
