started the GPS L2 FPGA class implementation (not finished yet) implemented the GPS L5 FPGA class (not tested yet) implemented the Galileo E5 FPGA class (not tested yet) The code is still "dirty": it is yet to be cleaned of debug comments/code and any possible redundant code and not used variables.
