/**********************************************************************
                nonlin()
***********************************************************************
Gives two outputs for bifurcation diagram
Input parameters:
	min_param: minimum parameter value
	max_param: maximum parameter value
	num_inc: number of increments
	length_iterate: number of iterations
CONTROL PARAMETERS:
	num_of_samples     = total number of samples to output.
	pace_rate          = multiplies the number of samples received 
			     on pace input (if connected) to determine 
			     how many samples to output.
	samples_first_time = the number of samples to put out on the
			     first call if pace input connected. It can
			     be zero. negative values = 0.
CONTROL DESCRIPTION:
If the pace input is not connected:
      The num_of_samples parameter sets the maximum number of samples
	that the star will output. If num_of_samples < 0, an indefinite
	number of samples can be output.
      The star will output a maximum of NUMBER_SAMPLES_PER_VISIT on each call.
If the pace input is connected:
      The num_of_samples parameter sets the maximum number of samples
        that the star will output. If num_samples_out < 0, an infinite
	number of samples can be output.
      The pace input paces the number of output samples on each call.
      At each call of the star all samples are read from the pace input
	and a running total of how many there have been is kept.
      An output_target  is computed at each pass = pace_input_total *
	pace_rate. If pace_rate < 0, the absolute value is used.
      On the first call:
	output = lesser of (samples_first_time, num_of_samples)
      On subsequent calls:
	output = lesser of (NUMBER_SAMPLES_PER_VISIT, output_target)
	   output_target = samples_first_time +
		 pace_rate * pace_input_total - to that point
      The total number of samples that will be output:
	samples_out_total = lesser of (num_of_samples,
		     samples_first_time + pace_rate * pace_input_total)
