Uses the enter frame event to provide a frame tick where the frame duration is the time since the previous frame.
There is a maximum frame time parameter in the constructor that can be used to limit
the longest period a frame can be.
Applies a time adjustement factor to the tick, so you can slow down or speed up the entire engine.
The update tick time is multiplied by this value, so a value of 1 will run the engine at the normal rate.
