Put sendto_time.c in the ppc/time_testing directory for future udp sending tests. Also added the other time_testing files used on the wiki page for testing the udp sending rate.

Added yappi.py inside apps to characterize run_minicoord.

Tested out get_clock_offset in catcher, not currently using it because it isn't working and get_clock isn't the bottleneck. May return to it later.

Minor changes to other files, used for debugging different things (clock vs data for example).
