Chapter 11 Raster Manipulation
*
A spur is defined as a line segment which is either connected on only one end,
or not connected at all.  The grow_spurs command will find all spur end 
locations on the raster & attempt to close it with another spur end, or 
by extending it into another raster object.  It uses the same logic as the
bridge_gap input mode.  NOTE:  a gap between two spurs will be closed up to 
twice the distance specified in the command.  A spur will only be extended up 
to the input distance into another raster object which is not a spur.  
NOTE:  If a closure cannot be found within the specified distance, the spur 
will be left alone (no pixels will be added).
