* This is an Android server implementation. It has as members a vrpn_Button_Server
* and some number of vrpn_Analog_Servers, as determined by the Java side. This
* implementation also has vrpn_Button_Remote and vrpn_Analog_Remote clients for
* the sole purpose of testing. All data from the Android is represented here
* as either Analogs or Buttons.
* All interaction between this class and the Java side are handled by the jni layer.
* It's worth noting that it is possible to pipe stdout to the Android log - directions
* for doing so are in the manual for this project - and all output is in the form of:
* fprintf(stderr, "..."), which we've found to be more reliable than other methods,
* including fprintf(stdout, "...").
