Function evaluates all its input samples through an expression
specified as a parameter to yield an output sample;
the number of input buffers is arbitrary and determined at run time.
The number of output buffers is also arbitrary (auto-fanout).
In the expression refer to the sample on input buffer 0 as in0, for
input buffer 1 as in1 and so on. For example:
	sin(5*PI*in0/100)*exp(-0.001*in1)
Note the PI is predefined.
