/*
Simple timer class
==================
History:
Created - Sarah "Voodoo Doll" White (2006/01/26)
==================
Description:
A quick and easy timer class to save people
from using ad hoc timers. The constructor
begins the timer and the end() member function
stops it, as well as returns the result.
Before starting the timer again with begin(),
users can see the last result with last()...
So unintuitive. ;)
==================
Bugs:
The timing method used is neither strictly
portable, though it only uses standard
functions, nor is it guaranteed to support
timing resolution less than a second.
