tre-fuzz

• agrep.c - modified to read the regex from stdin. This breaks agrep so that it isn't useful as a commandline utility but allows for easier fuzzing with afl-fuzz
• random - data file created from /dev/urandom and used during testing of regexes

Calling modified agrep

# agrep random random < id_filename
or
# cat id_filename | agrep random random

random must be listed twice because I tried to make as few changes to agrep.c as possible
