Changed the lib architecture. Now you don't need to change a define in the SBNetwork_config.h to change the device type from Master to Client. You can do this in the constructor ob SBNetwork class. The code get a little bit bigger now, because the lib always compiles for both master and client device. But it is definitively better to use now.
