//       Class : PStatTimer
// Description : A lightweight class that can be used to automatically
//               start and stop a PStatCollector around a section of
//               code.  It's intended to be used in the following way:
//               create a local PStatTimer variable to start the
//               Collector, and when the PStatTimer variable goes out
//               of scope (for instance, at the end of the function),
//               it will automatically stop the Collector.
