Fixed default parms bug on wave functionsAdded new "mix" operator (which misses a current value with generated one at generator wavefunc base)Added "random" and "randmap" wavefunction"random" returns a random value each frame"randmap" create a random-sized function and interpolates between it's points, parm1 (0-1) is roughness - 0 is flat, 1 is 256 control points.
