Detailed Description
The SigmoidFunction class implements the transfer function which is an discrete approximation of the sigmoid function.
In this case 2 mouse speeds are used as boundaries which are mapped onto 2 gain boundaries such that if the mouse speed is in-between 2 speed boundaries, then the corresponding gain value is computed by interpolating min and max gain values. Otherwise, minimum or maximum gain value is chosen.
