Summary stats for annotations

[clogan88]

This is an awesome pipeline! One additional suggestion would be to provide some summary stats for how many / what percent of genes and isoforms were annotated to the different databases (perhaps also including some way to quantify real annotations vs "uncharacterized protein", etc) . Also, including some code for how to convert the final parsed .csv file dammit contig IDs to the original Trinity contig names would be really useful.
