NAME
cdf_modeller - a modeller for netCDF files containing display_data
DESCRIPTION
The cdf_modeller is a convenience object that interfaces
the cdf_display_data_reader with modeller functionality.
That is, it reads netCDF display_data and then can be used
to draw it.
The cdf_modeller delegates all unrecognized messages to
its cdf_display_data_reader. Hence cdf_modeller responds
to all messages that the cdf_display_data_reader does
(e.g., "points_on!", "scalars_off!", etc).
Because the cdf_modeller is a subclass of new_modeller, it
responds to the "data?" message and can be used in the
display_data pipeline. In addition, cdf_modeller also
inherits the convenience routines from new_modeller (e.g.,
output!).
