Notes

Note: The QUIT button allows burning in the final curve and lists its
values. The LIST button lists the current curve parameters.

Equation file format: This file defines the equation, the x range
and range of each adjustable parameter. The file is a text file with
certain tags. Null and comment lines (* in first column) are allowed.
The tags are shown by an example:
eq: y = a + b*x + c*x^2
title: Parabola
xrange: -10 10
n_points: 100
par: a -50 50 0
par: b -50 50 0
par: c -10 10 1

The parameter tags are followed by 4 items: Parameter name (as in the
equation), min value, max value, initial value. An optional 5th item
may be the word int to force an integer value (for flags or harmonics).
