Plugin to easier grasp the method call hierarchy in a JAVA class.
The usability is not great at the moment. You have to press Ctrl+Alt+Q or use the menu entry in the CODE menu to test it. On top of that the colors are not configurable. At this state it's more or less a prototype :)
The zip file in the root directory contains a packed version of this prototype and may be installed via the settings menu of IntelliJ. Use the 'Install plugin from disc' button.
