	This module allows users to draw points in the geometry viewer.
The value of the point is mapped into color by the colormap of AVS.  The input 
field is a 1D 3 space field with (x, y, z, value).  

	Input Data: Field 1-D 3-Space 1-Vector IRREGULAR
                    Colormap (Optional)

	Output data: Geom

	This module belongs to a group of modules submitted to the Inter- 
national AVS Center for displaying points, lines and polygons over a map of the
United States. The group of the modules includes:

	AFSextract: 	 	Extracting AFS Format Data
	AMSextract:		Extracting AMS Format Data
	LBFextract:		Extracting Link Base Mobile Data
	field_to_points:	Plot 3D points with color mapping
	field_to_lines:		Plot 3D lines with color mapping
	field_to_polygons:	Plot 3D polygons with color mapping
	getmap:			Plot political boundary of states and
				countys in the United State
	geomreset:		Reset and normalize the geometry viewer
				automatically
	zoomer:			A driver to allow zoom in and out to a 
				particular geographical area
	resetlegend:		To reset the position and size of ithe color 
				legend if usedirregulr


	An example network is shown below:
