Point Cloud Fixed

Raver1975 pointed out that the PointCloud was broken !  I looked into and found a simple naming issue - its fixed, but some other thing I noticed was the abismal performance of the actual display.  The root cause of that known issue is it currently uses Java3D which has been a dead project for years.

There are a couple of promising projects to substantially increase display performance - One of which is https://jogamp.org/jogl/www/

Make note the data extraction and possible utilization by a robot is very proficient - this issue is around displaying that data only.

The fix is in MRL 1121.
