and data sets to generate notes, intervals, chords, scales, ...

Modules:
  
  Note.fromLatin(name): Note by latin name and octave

	Usage:
	
	var n = Note.fromLatin('A4');  // single note
	var freq = n.frequency();  // returns 440
	var name = n.latin();  // returns "A"
	var octave = n.octave();  // returns 4 
	
	var cmaj = Note.fromLatin('C4E4G4');  // chord = array of notes
	var freq = cmaj[0].frequency();  // returns 261.625...
	var name = cmaj[0].latin();  // returns "C"
	var octave = cmaj[0].octave();  // returns 4
	
	var n = Note.fromLatin('C4');  // base note for scale
	var majorScale = n.scale('major');  // scale = array of notes  
  
  
  Interval.fromName(name): Interval by name
  Interval.fromSemitones(num): Interval by semitones

	Usage:
	
	var fifth = Interval.fromName('fifth');  // define by name
	var wholeStep = Interval.fromSemitones(2); // define by # of semitones
	
	var c = Note.fromLatin('C3');
	
	// use intervals to transpose notes
	var d = c.add(wholeStep); 
	
	// use intervals to define chords
	var cmaj = c.add(['unison','major third','fifth']);
