RPKMS

this release introduces rpkm calculations and makes some summary tables based on the kraken output.

I also added a requirements.txt file, and you should pip install that as sometimes pysam can't be found and that breaks things.

v0.2 more goodness

Even more goodness for your metagenome analysis. Now with built in Pearson correlations!
