Subsample via normalization?

[BobLiterman]

Future thought: Instead of subsampling reads randomly, perhaps we could be assembling better genomes and getting more representative mapping if we instead:

1. Get raw reads for X species
2. Trim etc.
3. For 10X Mapping Data: Cat and normalize reads from each species by kmer to ~10X coverage (bbamp can do this)
4. For Genome Data: Subsample normalized reads to create genome data.
