Detailed Description

Proxy model that supports summary gantt items.

This proxy model provides the functionality of summary items. A summary item is an item with type KDGantt::TypeSummary and zero or more children in the model that it summarizes. GraphicsView itself does not dictate any policy for summary items, instead the logic for making the summary items start and end points span it's children is provided by this proxy.

The start and end times of a summary is the min/max of the start/end times of it's children.
