KZ_HEADER_BEGIN KANZI_API void kzcIntegrateExponentialDecay	(	kzFloat *	value,
		kzFloat *	derivative,
		kzFloat	halfLife,
		kzFloat	timeStep
	)

Integrates a variable whose derivative decays exponentially over a given time step.

Updates 'value' and 'derivative' with their values after the given amount of time. Parameter halfLife is the half life of the derivative.

Example: Movement of value 'x' starts with speed 'v' and 'v' halves every 2 seconds. Solution: kzcIntegrateExponentialDecay(&x, &v, 2.0f, deltaTimeMs / 1000.0f);
