Make a toggle list of embedded relationship types that can be shown #176
Description
In stig-v3, most embedded relationships are shown when the user selects Graph > Toggle Embedded Relationships
However, there could be a lot of embedded relationships shown that make it hard for an analyst to find what they want. It would be nice to have a list of toggle-able embedded relationship fields. The default is that all would be selected. Deselecting one would make all embedded relationships for a certain field disappear from the screen if they are on. This is a neat task, but is a low priority.
