GPLv3 and a README with a licencing statement for the initial release
since at this point all copyright holders agree on this.

moved library modules one up so they can be shared by several scripts (each contained in a separate directory)

added small scriopt to dump the status of the 53230 so see if we can find differences in status when it behaves fine and when it behaves erratic.

changed levels according to use of MiniCircuits Splitters ZFRSC-123+ which have ~ 6 + 3,75 dB attenuation (~ factor 3).

Nowadays we are at scipy.__version__ 0.17.0 which failed to define "argrelmax". "if 1" always define!
