docstring: Return the angle of the line from the turtle's position to (x, y).
  
          Arguments:
          x -- a number   or  a pair/vector of numbers   or   a turtle instance
          y -- a number       None                            None

          --or: distance(mypen)        # where mypen is another turtle
  
          Return the angle, between the line from turtle-position to position
          specified by x, y and the turtle's start orientation. (Depends on
          modes - "standard" or "logo")
  
          Example (for a Turtle instance named turtle):
          >>> turtle.pos()
          (10.00, 10.00)
          >>> turtle.towards(0,0)

docstring_summary: Return the angle of the line from the turtle's position to (x, y).
docstring_tokens: Return the angle of the line from the turtle s position to ( x y ) .
