Epitope prediction : new module added.

-Adds genomic coordinates to predicted epitopes.
-Takes in parsed file generated from  ParseNetmhcOutput.pm and SNVs file as input.
No change needed but wanted to share that I often use `q()` instead of single quotes and `qq()` instead of double quotes to avoid having to escape quotes in a string.  So, for example, this could be:
```
q(Takes in the "Parsed" output...)
```
