Implemented a more sane way of handling SIGINT
Implemented a more sane way of handling SIGINT

[ ENHANCEMENT ]  User interruption of script is now handled much
more sanely (via EXIT -- rather than SIGINT/SIGTERM)

[ ENHANCEMENT ]  Exit code for user interruption (SIGINT) is now
'130' for each operation

[ ENHANCEMENT ]  As a result of the above changes, each operation
no longer needs to be done as a child process allowing for future
error messages to be more verbose (ie, based off the programs'
STDERR output)

[ EHNANCEMENT ]  Comment cleanup and various comment additions
