HEK two different F/Es are co-spatial

[Jack Ireland]

This bug is slightly different to bug #1180816 HEK F/E flares and other events that are co-spatial. That bug refers to co-spatial F/Es where all the F/Es are of the same type.

Close to disk center, flares and filament eruptions are co-spatial. These are two different F/E types. How are we to handle two or more different co-spatial F/E types?

There are relatively few cases of this in the HEK dataset. Calculating when any two events are co-spatial would slow the plotting of F/Es down. Also, the criteria for when are two events co-spatial enough are not clear. A partial solution has been implemented via mouse-over the checkbox rows, and the event markers/labels. These mouse-over events highlight the selected event, even if it initially appears "underneath" an overlying event.
