Annotation for context specific sequencing error regions

Aaron;
In our continued quest for diagnostics to help identify potential false positives, this integrates regions associated with sequencing errors from a recent paper Oliver spotted in BMC Bioinformatics:

http://www.biomedcentral.com/1471-2105/14/S5/S1
https://code.google.com/p/discovering-cse/

This adds docs, provenance and database updates. At some point the annotation files will need to be moved over to the main repo but should work cleanly as is from my AWS S3 bucket.
