/**
* WARNING: Requires Spring 1.2.8 or newer libraries in the classpath <br/>
* Makes it easier to write {@link EntityProvider}s in webapps <br/>
* A class to extend that gets rid of some of the redundant code that has
* to be written over and over, causes this provider to be registered when it
* is created and unregistered when it is destroyed, also includes the
* {@link DeveloperHelperService} as a protected variable,
* pairs with the parent bean (org.sakaiproject.entitybroker.entityprovider.AbstractEntityProvider)<br/>
* Create your spring bean like so (class is your provider, set whatever properties you are using):
* <xmp><bean parent="org.sakaiproject.entitybroker.entityprovider.AbstractEntityProvider"
class="org.sakaiproject.entitybroker.entitywebapp.WebappEntityProvider">
<property name="dao" ref="MemoryDao" />
</bean></xmp>
