bollingerbands(src, lkbk, mult, basis)
  Bollinger Bands
  Parameters:
    src (float): float
    lkbk (int): int
    mult (float): float
    basis (float)
  Returns: Bollinger Bands

donchianchannels(src, lkbk, band_width)
  Donchian Channels
  Parameters:
    src (float): float
    lkbk (int): int
    band_width (float): float
  Returns: Donchian Channels with an outer band of varying thickness adjusted by the band_width input

doublehalfdonchianchannels(src, lkbk, divisor)
  Double Half Donchian Channels
  Parameters:
    src (float): float
    lkbk (int): int
    divisor (float): float
