Working on converting a Proj4 string and writing the resulting GeoKeys to file.
Proj4StringParser working, just using it in the encoder and writing some tests then done.
Proj4String implemented in writer, testing is left.
CRS information writing correctly. Still errors opening the written GeoTiff in MAC OS X default image program. To fix this is the next step.
Fixed test cases. Still having problems with the writer.
Very minor polishing.
Fixed Travis compile errors.
