Interpolates between mesh object attributes or assigns values to a mesh object attribute.

Options constant and gaussian assign values to a mesh object attribute.  Options table, integer1, and integer2 interpolate from a reference mesh object.

The constant option assigns a constant value to all specified nodes.

The gaussian option creates a very special gaussian distribution around a line or point.  The bounding box (x1,y1,z1) to (x2,y2,z2) specifies where the peak concentration will be, Note: y2 is ignored; if z1=z2 then the distribution will be around a point.  All coordinates are assumed to be given as Cartesian, xyz is required.  The value assigned to the attribute is determined by the Gaussian distribution:

value = concentration
