Create crispr-scf-scanner.pl

This script takes a directory of .scf sequence trace files and pattern matches against a defined list of CRISPRs. 
Useful for off-target validation of sequenced PCRs where you don't want to manually look through them all. It doesn't do alignments, just simple pattern matching so if your sequence traces aren't good you may run into problems. 
Any non-matches are flagged for manual processing

Output file shows the original crispr, the off-target match, strand and scf file name
