Interface for tools. A tool is a collection of rules binding user input (e.g., keyboard and mouse events) to display and data manipulation in a coherent way.
For example, a PanTool might pan a display when the mouse is dragged or arrow key is pressed, while a PencilTool could draw hard lines on the data within a display.

Tools discoverable at runtime must implement this interface and be annotated with @Plugin with Plugin.type() = Tool.class. While it possible to create a tool merely by implementing this interface, it is encouraged to instead extend AbstractTool, for convenience.
