Sometimes you want to make sure that your "faster" algorithm really is
faster than the old way. This lets you check. It might also be useful
to check that your super whizzo XS or Inline::C version is actually
faster.

This module is based on the standard Benchmark module. If you have
lots of timings to compare and you don't want to keep running the same
benchmarks all the time, you can pass in a result object from
Benchmark::timethis() instead of sub routine reference.
