Detailed Description

A class that can be used measure time on Linux systems.

A timer class that uses the linux function gettimeofday() to measure time. The resolution can vary on different systems but is usually a few micro seconds. Can be checked with getResolutionUs(). Stores all times taken, between a start and a stop, as seperate runs and they exists until timer is reset. Both total time of all runs and average can be returned.
