## Class BrownianLinePath

              BrownianLinePath

Line, with random motion superimposed.

Need to be careful that maxRandomness does not swamp out the motion along the line.

Might be good to limit maxRandomness to less than distance/steps

Method Summary
| `__init__(self, startLocation, endLocation, maxRandomness, steps)`
Inherited from ListPath
| ``next`(self)` return position
| ``reset`(self)` put path back to original state
| ``set_loop`(self, loop)` Set number of times to go around path.
| ``set_timePerPlace`(self, duration)`
| ``_oneLoop`(self)` Check if should continue looping.
Inherited from Path
| ``__iter__`(self)`
| ``get_direction`(self)` Return the direction from the previous location to the current location.
| ``get_position`(self)` Return position along Path
| ``get_x`(self)` return x component of position
| ``get_y`(self)` return y component of position
| ``onscreen`(self, slack)` true if path position is on main window
| ``pause`(self)` stop moving along path
| ``set_endTime`(self, duration)` Path will raise StopIteration after self.duration seconds
| ``set_position`(self, position)` Set position and update positionOld
| ``unpause`(self)` resume moving along path
