Hello Peter,

To define the sensor:

- define a node ==> 

- define a segment (this could be a dummy LAG segment) that this node belongs to so the code can establish a normal vector ==> 

- define the offset distance along that normal => a sensor will be located at the tip of that vector

a "sensor" will be attached to a Lagrangian segment/node and moves with it.
the p inside the ALE elm which is passed by by this sensor is saved.  The
p history result may plotted from either the binary file or ASCII file output (user can choose)
