Section Interfaces

<p>
	Config sections can also be accessed via interface proxies using 
	{@link oaj.config.Config#getSectionAsInterface(String,Class)}.
</p>
<p>
	While section maps and beans retrieve copies of the configuration data at the time of the method
	call, section interfaces can also be use to set values in the underlying configuration.
</p>
