Detailed Description
A very simple lightweight benchmarking tool. Call Timer::Reset() to reset the timer and Timer::Print() to print the time elapsed to stdout.
Usage:
Timer::Reset(); //do something Timer::PrintAndReset("First thing"); //do something else Timer::Print("Other thing");
which outputs (for example):
First thing time: 10s Other thing time: 2s
