Exports functions for calculating perceived dissonance of musical frequencies:

calculateDissonance(frequencies: [float]) Uses Sethares' Dissmeasure Algorithm to evaluate the dissonance score of any number of frequencies.

dissonanceMatrix(matrix: [[[float]]]) Takes in an array of array of array of frequencies (where f[i][j] is a list of frequencies) and returns the indexes i & j as a two-element array such that f[i][j] gives the lowest dissonance score amongst all the list of frequencies in the matrix. See https://github.com/euwbah/31edo-lattice-visualiser/blame/9b76985ca53ab4319f0e742cd7175b2a10c7344e/harmonic-context.js#L105 for usage.

findOffender(frequencies: [float]) will return the index of the frequency that, when removed from the list, will result in the largest drop in dissonance score. The last element of frequencies will not be regarded as a potential candidate.
