new InteractionController(widget)
Tool object that manage the interaction (mouse, key event) of a UI widget.
A component may have multiple controllers, for example, in Ctab based editor, select tool is used to select nodes and connectors,
bond tools is used to draw new bond, charge tool is used to assign charge... Different tools have different function and must
response differently when a event is occured. So different tool object is used to cooperate with editor.
Tool object has a set of methods to handle events (reactMouseMove, reactMouseClick, etc). If the event is handled, the method must
return true, otherwise the event will be handled by default tool.
