Adds new Gantt Chart Lite control, new container types and activity filtering.
New GanttChartLite control inherits from the new base class called GanttChartBase. The lite version only consists of the timeline and the graphics area.
New container type - The quad container displays four Gantt charts at the same time and synchronizes the timeline scrolling between the two charts on the left-hand side and the two charts on the right-hand side.
Added activity filtering - GraphicsBase.setActivityFilter(Predicate filter); Acts only on the UI layer, it does not have any impact...
