renamed reverb effect to 'echo', since reverb will be reserved to a more complex effect to simulate accoustic environments implying multiple echoes effects
added example of rudimentary chiptune instruments including arpeggiator
added jasmine.js lib to test MUSIC.Utils.Scale
refactor test to avoid repeating scale naming data
make 4 faling tests for C major scale pass
added passing tests for all octaves
56 new failing tests for octave displacement note aritmethic
made 56 failing test pass (note scale aritmethic
added 8 failing tests for note different from C addition on C major scale
+8 test pass, addition to notes different from C on C major scale
refactor on tests: using multiple scale testing
+108 failing tests: D major and E major scale maths
+68 passing tests: implemented logic for nextNote according to scale base
+25 passing tests: nextNoteHash for E major scale
+20 passing tests: implemented cyclic nextNote logic on scale
+4 passing test: fixing cycling hash for D major scale
refactor: created nextNoteHash from base semitone
refactor: rewrite algorithm for scale math add using truefalse hash for fulltoneadd per notenum
using scale maths utils on chiptune example
added noise instrument to simulate kick on chiptune set example
