Version 1.1 - 25 Nov 2020 - Eric E. Palmer
Given an image and a bigmap, determines local phase, emission angle, and incidence angle and writes them to a TXT file. Also output other data, including a text file for the latitude and east longitude of each pixel (which is independent of the image chosen).

=== Input - files ===
 * JRW believes there are none required. Just need MAPFILES, SUMFILES, and NOMINALS directory.

=== Input - stdin ===

 * Bigmap name (six characters)
 * Image name (12 characters, can use symbolic link if actual name is > or < 12)

Example
{{{
IN1ED1
XXXXXXXXXXXX
}}}


=== Output ===
 * <bigmap>-a.TXT - local phase: Orientation is the same as SHOWMAP for the bigmap
 * <bigmap>-e.TXT - local emission:  Orientation is the same as SHOWMAP for the bigmap
 * <bigmap>-i.TXT - local incidence:  Orientation is the same as SHOWMAP for the bigmap
 * <bigmap>-h.TXT - x slope: Orientation is ???
 * <bigmap>-v.TXT - y slope: Orientation is ???
 * <bigmap>-lat.TXT - latitude: Needs to be flipped top to bottom, then rotated 90 degrees clockwise to agree with SHOWMAP for the bigmap
{{{
flip from=INGV02-lat.cub to=INGV02-latFlip.cub
}}}
 * <bigmap>-lon.TXT - east longitude: Needs to be flipped top to bottom, then rotated 90 degrees clockwise to agree with SHOWMAP for the bigmap
{{{ 
rotate DEGREES=90 INTERP=NEARESTNEIGHBOR from=INGV02-latFlip.cub to=INGV02-lonFlipRot.cub
}}}
