Tool (gephi 0.9.3 API)

```
public interface Tool
```
Tools are functions for interacting with user inputs on the visualization window.
A tool receive events from visualization window when it is currently the selected tool. The visualization window toolbar presents all available tools implementations.
Example: A Brush tool colors clicked nodes.
How-to create a tool implementation
1. Create a class which implement Tool interface
2. Add the following annotation to your class to be declared as a new implementation @ServiceProvider(service=Tool.class)
3. Declare ToolEventListener instances for specifying how the tool is interacting with user input like node click or mouse drag.
4. Provide a ToolUI instance for giving a name and an icon to your tool.
