Pynetmhcpan

Fixed
- Wrong path was used to make temp directory.

New
- A unique temp directory is used for every analysis. This makes it possible to run multiple instances at once,
e.g. on a computing cluster.

Fixed
- Config file was _still_ missing when installed from PyPI because I messed up the filename of MANIFEST.in

Fixed

New
- Added `annotate_file` function to `NetMHCpan.Helper` class. This reads an input file (e.g. a PSM file), makes
binding predictions based on the contents of the indicated peptide column (default is `Peptide`), and in a new
compy of the file writes the binding percent rank from NetMHCpan as a new column.

New
- Everything! First release of the project.
