/**
* Ant task for generating WADL for root resource classes.
*
* The task requires that the destfile attribute be set to the location
* of the WADL file to be generated, the baseUri attribute set to the base
* URI of the WADL resources, and the classpath be set.
*
* The task will scan all classes in the classpath obtain the root resource
* classes and then create a WADL document from those root resources.
