[Contrib] An importer for csv files

[simpsus]

https://github.com/simpsus/WordCram/blob/sketches/src/contrib/CSVImporter.java

can be given a csv file and two indices. The csv file will then be parsed and a Word[] returned. The csv parsing is handled by the lightweight opencsv http://opencsv.sourceforge.net/ https://sourceforge.net/projects/opencsv/ for which there seems to be a fork at https://code.google.com/p/opencsv/ which I did not use
