// Timer.h
//
//	Abstract class that defines the interface for a high resolution timer
//
//	A timer should implement 3 methods:
//		* getTime, that returns the actual number of ticks.
//		* getTicksPerSecond, that returns the number of ticks in a second.
//		* sleep, that stops execution for a specific time.
