Epitope Prediction : New Module Added

New module to filter based on binding affinities and merge results from different allele-length combinates.
For some reason, on replacing my code with the above-mentioned snippet, I keep getting this error -
ERROR: Can't use string ("<samplename>") as a HASH ref while "strict refs" in use at /gscuser/jhundal/git/genome/lib/perl/Genome/Model/Tools/EpitopePrediction/BindingFilter.pm line 107.

Here <samplename> refers to the sample I used to test the code.
