## Predefined Constants

`LuaSandbox::SAMPLES`

  Used with LuaSandbox::getProfilerFunctionReport() to return timings in samples.

`LuaSandbox::SECONDS`

  Used with LuaSandbox::getProfilerFunctionReport() to return timings in seconds.

`LuaSandbox::PERCENT`

  Used with LuaSandbox::getProfilerFunctionReport() to return timings in percentages of the total.
