  once._        A place to put functions that run once

  always._      A place to put functions that run continuously

  cached(f)(-)  Caches value of f applied to JSON'able arguments

  clear()       Clears vars, once, always, cache, setTimeouts, canvas

  using(url)    Loads & caches a remote script (useful for libraries)

Coding Tools

  help(-)       Looks inside any object/function (great for hacking :)

  print(-),     Print messages to log area

  error(-)

  assert(-,-)   assert(value,message) throws an error if value is false

                (see help(assert) for details & other assertions)

  TODO(-)       TODO(message) is a placeholder for unfinished code

Graphics - using HTML5 canvas

  draw          A 2D canvas context (see examples)

  mouseX,       Current mouse coordinates in pixels

  mouseY

Audio - using HTML5 audio

  play(-)       Plays a uri from encodeWav/tone/noise/speech or the web

  encodeWav(-)  Encodes an array of [-1,1]-valued samples to a wav uri

  tone(-),      Synthesize sound and encode to wav uri

  noise(-)      (see examples or try help(-) for details)

  sampleRate,   Constants in kHz (all time units are ms or kHz)

  middleC
