<P>
ModuleActivator represents a module that plugs into the Tuscany system. Each
module should provide an implementation of this interface and register the
ModuleActivator implementation class by defining a file named
"META-INF/services/org.apache.tuscany.core.ModuleActivator"
The content of the file is the class name of the ModuleActivator implementation.
The implementation class must have a no-arg constructor. The same instance
will be used to invoke all the methods during different phases of the module
activation. Note that the start and stop methods defined by this interface
take a reference to the Tuscany SCA runtime ExtensionPointRegistry. This
gives the ModuleActivator the opportunity to add extension points to the
registry as it is requested to start up and remove them when it is requested
to shut down.
