/**
* @file Profile.h
*
* Very simple profiling macros. Place PROF0(id) / PROF1(id, n) pairs
* around the code you want to time. The 'id' parameter must be a unique
* identifier (valid C identifier) that will be used to label the test.
* The 'n' parameter is the number of times to average before recording
* the result to the log file. Logging goes to the PROFILE target, so
* you must enable this (--log=PROFILE on the CSPSim.py command line) to
* see the timing results. Each log entry contains the 'id' identifier
* and the average execution time in milliseconds.
*
