Renamed directory to  for consistency with website
Update to transcriptome assembly pipeline.

     Step 1) Still cutadapt and FastQC
NEW  Step 2) Use FLASH to merge paired-end reads that overlap. Reduces total reads while extending length
     Step 3) Use 'diginorm' to normalize reads to further reduce read redundancy and eliminate errors

Next...assemble with velvet. Should take MUCH less memory after data reduction steps
