# Program:      modCheck 
# Date Created: 29 January 2009 
# Developer:    **** (Digital Sys. Admin)
# Revised:      21 June 2009; Rewritten to simplify code, added color, ability to dynamically check for number of DeMODs
# Revised:      24 June 2009; added dumping to log file, added ability to use IP and MOD name
# Revised:      14 July 2009; added ping check
# Description:  Generates report of box signon for a given mod
# Last Updated: N/A
