ListPlot documentation has disappeared

[rocky]

Description

Recent changes to the plotting class structure have caused functions subclassed with _ListPlot to disappear.

How to Reproduce

Go into Django. Click on "?" and type "List"

Output Given

Expected behavior

ListPlot should appear and the documentaiton and examples for that should also appear

Your Environment

Current master environments for mathics-core and mathics-django

Workarounds

Use last version

Priority

Additional context

I think this is just a matter of subclassing or changing the code that produces documentation to include _ListPlot to the list of classes that we look for documentation.

There haven't been any changes to the class structure (barring errors), but there have been changes to the module structure: plot.py was split into plot.py, plot_chart.py, plot_listplot.py, plot_plot.py, plot_plot3d.py according to base class. So all the _ListPlot subclasses are in plot_listplot.py. Will this confuse the documentation system - does it have module names hard-coded? In any case I'm not sure how this change could affect _ListPlot and not the others since all were split out in a similar manner.

One thing that's going on is that there should be a docstring at the top describing what that section does. See, for example, the top of drawing_options.

Also, the from .plot import sort_order is probably funky too. This indicates how to arrange the sections and if that's not there, the module name is used.

When I run remake inside mathics/doc/latex, I see the documentation structure:
