Added function to return all translations of a DNA sequence, tests, and a dumb function to get the length of the maximum ORF from a translated sequence.
Removed debugging print statements.
Added dna-to-aa.py script. Made fastaReads accept a file handle as well as a file name. Moved formatting as FASTA or FASTQ of a read into the read class. Added 'rc' to id of translated AA sequences that come from a reverse complemented read.
Fixed docstring indentation.
