Improve DvEG schematic

The documentation page for DvEG analysis schematizes the concept using a combination of Platt graphs and boxplots. However, there are too many components to hold in your head. In particular, it is confusing to relate the highlighted child in the WT vs MT plot to the normal expression patterns in the parent-child plot.

I think it would be much simpler to present the concept as a single line plot with two colors. The x-axis is parent and child, the y-axis is gene expression, one line is the WT condition and one line is the MT condition. In example 1 (gene goes up, but is underexpressed in MT), the WT line would go up while the MT line would be flat (or have a smaller slope).

The plots have different x-axis: parent v. child across nodes and mt v. wt in a single node, so I'm not sure you can have a single line plot?
