Major API overhaul. Moved to a single data structure for handling render functions. Functionally, generally similar except for scheduling within PRU loop function, which now uses interrupts from the PRU rather than polling. This requires an updated kernel.

Three simple c scripts can be used to test the network, in conjunction with the basic_network project:
udp-client.c, udp-client-sweep.c,d udp-server.c
compile them with gcc -o udp-client udp-client.c and similar
They can be compiled and run from either the host or the bbb

usage
./udp-client 192.168.7.2 9998 #sends individual messages to the bbb on port 9998
#enter desired values for frequency (and phase).
123.0;0;

The parser is currently very stupid, so the format of the message has to be::
frequencyValue;phaseValue;
example:
700.0;0.1;

./udp-client-sweep 192.168.7.2 9998
sends messages every 1ms to control the frequency of the oscillator, thus generating a sine sweep

./udp-server 9999
#will print the info received from BeagleRT with the following format
printf("%8d;%.3f;%.3;",gCounter,gFrequency,gPhase);
example:
88201;700.000;0.123;
