  adapted from http://en.wikipedia.org/wiki/HSV_color_space.
  Assumes h, s, and v are contained in the set [0, 1] and
  returns r, g, and b in the set [0, 1].
  
  @param   Number  h       The hue
  @param   Number  s       The saturation
  @param   Number  v       The value
  @return  Array           The RGB representation
