Create python wrapper for a kmer counting utility  implemented in  C++

https://github.com/uni-halle/gerbil is a state of the art kmer counting utility with GPU support. It is used standalone from the command line.  but it would be great if it could be called from Python so that it could count kmers in sequences referenced by a Python variable and, as it does now, from files and then return counters as a Python dictionary.
