* To work around this problem, we try a couple of Newton-Raphson

* iterations to see if the true root is closer to the endpoint
|

* or further away. If it is further away, then we can stop
|
||||
* since we know we are on the right side of the endpoint. If
|
||||
* we change direction, then either we are now being dragged away
|
||||
* from the endpoint in which case the first condition will cause
|
||||
* us to stop, or we have passed the endpoint and are headed back.
|
||||
* In the second case, we simply evaluate the slope at the

* endpoint itself and place ourselves on the appropriate side
