#****c* Scripting/scripting::scalarField2D
#
# NAME
# scripting::scalarField2D
#
# PURPOSE
# Encapsulate the scripting interface for manipulating the 2D scalar
# field and display of isosurfaces and colorplane+contour plots. A
# typical usage of the interface is the following. First the scalar
# field is loaded with the "load" command. Then with the "configure"
# command the isosurface and/or contours display parameters are set.
# Finally the isosurface and/or contours are displayed using the
# "render" command. It is possible to make several snapshots of
# isosurface and/or contours by changing configuration options, this
# would look as:
#
# load
# configure ...
# render
# configure ..
# render
# ...
#
# COMMANDS
#
# -- scripting::scalarField2D::load
# Loads the scalar field.
#
# -- scripting::scalarField2D::configure
# Configure the display parameters for isosurface and/or contours
# plot.
#
# -- scripting::scalarField2D::render
# Renders the sosurface and/or contours.
