Move old PlotGrid logic to new CustomPlotGrid logic #2
Description
Regular plot grids should be a specific type of generalized (custom) plot grid. Old plot grid class structure does not allow for doing things like plotting horizontal cuts & vertical cuts of 3D sims with proper aspect ratio.
To do:
- Make CustomPlotGrid class the main PlotGrid class in plot_grid.py
- Make RegularPlotGrid (what the current PlotGrid class is) a subclass of PlotGrid
- Make ColorbarPlotGrid a subclass of new PlotGrid, where cbar always = True (very simple to code). Or get rid of it?
