Detailed Description

A PlotSelectTool is a concrete subclass of PlotMouseTool that mainly handles select events.

Note that plotting implementations may wish to override this class with an implementation-specific version that may be more efficient. PlotSelectTool is responsible for: 1) managing the select line (the line show while the user is click-dragging to select a region on the canvas) and cursors, 2) keeping track of selected regions, 3) showing/hiding the regions on the canvas, and 4) notifying any interested classes whenever the selected regions changes.
