// Description:   Generate a set of interval weights from a parameterize
//                spatial configuration of pitches.
//
// Models:      * Diatonic (slightly chromatic) the default method
//              * Single-Angle chromatic --  -t option ranges from 0 degrees
//                to 90 degrees.  0 degrees is equivalent to diatonic model.
//              * Double-Angle chromatic -- -t options is the same as before,
//                --t2 is the secondary angle from -45 to +45 degrees.
