IPlugger (JCommon 1.0.7 API)

All Known Implementing Classes:

DefaultPlugger
```
public interface IPlugger
```
This class represents a plugger. A plugger is the interface between the kernel of the application and the plugins. The main method of the plugger is getExensionPoint(String) which return an extension point that can be accessed by the plugins. The extension keys can be obtained by the method getExtensionPointKeys().

A class implementing the interface IPlugin can also implements the IPlugger interface. So a plugin can also be a plugger and can be extended by others plugins.
