docstring: Turn turtle left by angle units.

          Argument:
          angle -- a number (integer or float)
  
          Turn turtle left by angle units. (Units are by default degrees,
          but can be set via the degrees() and radians() functions.)
          Angle orientation depends on mode. (See this.)
  
          Example (for a Turtle instance named turtle):
          >>> turtle.heading()
          22.0
          >>> turtle.left(45)
          >>> turtle.heading()
          67.0
