CompositeFunction

Multiplies an arbitrary set of functions together

Description

The CompositeFunction type takes an arbitrary set of functions, provided in the functions parameter, evaluates each of them at the appropriate time and position, and multiplies them together. The function can optionally be multiplied by a scale factor, which is specified using the scale_factor parameter.
