TABLE_DENSITY

##
TABLE_DENSITY

               Compute a 2-D image with the density of points
           from 2 columns of an input table. Also create a table
           containing only the "isolated" points, those with a
           density below some threshold.

           The task is used by the  "plot-triangle.greg" procedure
           to display correlation analysis of N parameters, from a
           M x N table containing M valid samples of the N parameters.
