ConfigStore Listeners

<p>
	The <c>ConfigStore</c> class has the following listener methods:
</p>
<ul class='javatree'>
	<li class='jac'>{@link oaj.config.store.ConfigStore}
	<ul>
		<li class='jm'>{@link oaj.config.store.ConfigStore#register(String,ConfigStoreListener) register(String,ConfigStoreListener)} - Register a listener on the specified config name.
		<li class='jm'>{@link oaj.config.store.ConfigStore#unregister(String,ConfigStoreListener) unregister(String,ConfigStoreListener)} - Unregister a listener on the specified config name.
	</ul>
</ul>
<p>
	Note that this is a different listener than {@link oaj.config.event.ConfigEventListener}.
	In this case, we're just listening for changed files:
</p>		
<ul class='javatree'>
	<li class='jic'>{@link oaj.config.store.ConfigStoreListener}
	<ul>
		<li class='jm'>{@link oaj.config.store.ConfigStoreListener#onChange(String)} - Called when file changes.  New contents are passed in.
	</ul>
</ul>
<p>
	This listener is used by the <c>Config</c> class to listen for changes on the file system so that it can be
	updated in real-time.
</p>
