 Will execute as a cronjob every evening @10PM.
 The "SequencingResults" dir is where the search will begin.
 The script will search subdirs based on the date.
 If the current date is " 01-16-09", then the path will
 be "SequencingResults/RESULTS 2009/JAN 2009/Results 01-16-09".
 If the first file has either LacZ|pgK|SD|SU then it will mv that file
 to $seqdir. It will do this recursively for each file.
