  @method truncate(<length>, [split] = true, [from] = 'right', [ellipsis] = '...')
  @returns String
  @short Truncates a string.
  @extra If [split] is %false%, will not split words up, and instead discard the word where the truncation occurred. [from] can also be %"middle"% or %"left"%.
  @example
  
  'just sittin on the dock of the bay'.truncate(20)                 -> 'just sittin on the do...'
  'just sittin on the dock of the bay'.truncate(20, false)          -> 'just sittin on the...'
  'just sittin on the dock of the bay'.truncate(20, true, 'middle') -> 'just sitt...of the bay'
  'just sittin on the dock of the bay'.truncate(20, true, 'left')   -> '...the dock of the bay'
