RE: Subsection of Mark IV image with WCS keywords

["Albertson, Chris" <CAlbertson@primeadvantage.com>]

Parsing trick:  Just give everything between the colons
to "atoi()"  Pass ":" to strtok() to find what's between
the colons.  This will read just about anything including
real weird strings like "1: 000034 : 56"
and take all of about three lines of code.
sscanf() gives better error diagnostic then atoi() so it
may be better.
