/*********************************************************************
                slice()
**********************************************************************
This star simulates a decision element for a data receiver.
It compares the incoming signal to a set of thresholds, which are
COMPUTED from the user-specified set of output levels.
Thresholds are always exactly HALF way between specified output levels.
Output levels are specified via a topology file parameter array.
Parameter arrays are float, so there are no restrictions on specified
output values.  Only 10 levels are allowed, and must be listed in
ascending magnitude order.
	Examples-- binary decision (threshold = 0.0)
			param array 2 -1.0 1.0
		   quaternary decision (thresholds -2/0/2)
			param array 4 -3.  -1.  1.  3.
The number of output channels is determined at run-time (auto-fanout).
