/*
!C******************************************************************************
!Description: 'main' is the main function for the 'resamp' program.
!Input Parameters:
argc number of run-time (command line) arguments
argv list of run-time argument values
!Output Parameters:
(returns) status:
'EXIT_SUCCESS' = okay
'EXIT_FAILURE' = fatal error
!Team Unique Header:
! Design Notes:
1. See 'USAGE' in 'parser.h' for information on how to use the program.
2. An error status is returned when:
a. there is a problem getting runtime parameters
b. there is a bad input image, geolocation or kernel file
c. unable to set up the input grid, scan data structure,
or the output space
d. unable to generate kernel
f. unable to free memory for data structures
g. unable to set up intermediate patches data structure
h. there is an error reading geolocation for a scan
i. there is an error mapping a scan
j. there is an error generating geolocation for a scan
k. there is an error copying a scan
l. there is an error extending the scan
m. there is an error reading input data for a scan
n. there is an error resampling a scan
o. there is an error writting patches to disk
p. there is an error closing input image, geolocation, kernel or
output files
q. there is an error untouching patches
r. there is an error creating output image file
s. there is an error opening output file
t. there is an error unscrambling the output file
u. there is an error writing metadata.
3. Errors are handled with the 'LOG_ERROR' macro.
