public class ModeSelect

extends FigModifyingModeImpl

This class implements a Mode that interprets user input as selecting one or more Figs. Clicking on a Fig will select it. Shift-clicking will toggle whether it is selected. Dragging in open space will draw a selection rectangle. Dragging on a Fig will switch to ModeModify. Dragging from a port will switch to ModeCreateEdge. ModeSelect paints itself by displaying its selection rectangle if any.

Needs-More-Work: this mode has more responsibility than just making selections, it has become the "main mode" of the editor and it has taken resposibility for switching to other modes. I should probably implement a "UIDialog" class that would have a state machine that describes the various transitions between UI modes.
