<#
Purpose: Parses a list of user-submitted GUIDs against Tron's by_GUID list.
Removes all lines that are already in the by_GUID list, then outputs new unique lines to a new file
Requirements: Specify path to master GUID file, incoming file to check against, and output file
Author: reddit.com/user/vocatus ( [email protected] ) // PGP key: 0x07d1490f82a211a2
History: 1.0.3 * Simply whitespace removal block, use regex instead of multiple repetitive statements
+ Add extraction of "Intel" entries into separate file
1.0.2 + Add extraction of common entries ("CCC", "Microsoft" etc) into separate files for easy review
1.0.1 + Add auto compilation and cleanup of incoming GUID lists
1.0.0 Initial write
Usage: Make sure paths are specified correctly (variables below) then run the script

# * NO trailing slashes on paths! (bad: "c:\directory\" )
# * Spaces are okay (okay: "c:\my folder\with spaces" )
# * Network paths are okay (okay: "\\server\share name" )
