Adding standard performance testing files for k-nucleotide
Adding files to generate and use fasta input files
Clean up /Users/bharshbarg/chapel/edge/test/tmp when done with start_test
Clean up .../test/tmp directory when done with start_test
Adding performance files for reverse-complement
More RBC cleanup.

Remove extra .good and .prediff, and update comment.
Update default RBC test size so correctness testing runs faster.

Perf testing will still use the original problem size from the paper.

Fixing typo preventing start_test from cleaning test/tmp
Merge branch 'stdin-in-execopts' into fasta-stdin-perf
Better parallelization for regexdna
A new version using a chaining hash table
New version using an associative array
Merge branch 'master' into knucleotide
Using new readline for revcomp-begin
Improving safety of readline
Small performance and correctness improvements
Improvements to IO
Merging to use 'start' param with new readline functionaltiy
Better error handling if we go off the end of an array's domain
