[Sidefx-houdini-list] finding nearest and furthest distances

To get the closest point is easy because there are built-in functions
to find them.  You could write a small script that ran the nearpoint
or pointdist functions on each object in the scene using the camera's
origin as the reference point.

To get the maximum distance you could try taking a bounding box
of each object and measuring from the camera's origin to each
corner of the box using the distance function to find the largest value.
