local profiler = {}profiler.names = { }profiler.counts = { }profiler.times = { }profiler.timers = { }

The profiler module will have two important public functions: start and stop. These functions will start and stop the profiler, respectively. The profiler module will have an internal function, private_hook. The start and stop functions ...
