DESCRIPTION
    UV_SECTOR generates a geometry which is a sector of a circular annulus,
with UV coordinates>

    The geometry of the mesh is determined by the input parameters.  The
Resolution parameter determines the number of mesh nodes in both directions.

    The UV coordinates are set from 0,0 to 1,1 over the extremities of the
mesh.

    The purpose of the module is to demonstrate the ability to warp an
image (eg cartographic dataa) by texture mapping it to a geometry whose shape
can be varied.

OUTPUTS
	Output Mesh - geometry

PARAMETERS

        Min radius
        Max radius
        Min theta
        Max theta
        Resolution

OUTPUTS
	output - colormap
