<DL>
<DD>Initialize the module, passing it its peer group and advertisement.
 
 <p/>Note: when subclassing one of the existing PeerGroup implementations
 (which implement Module), it may not be recommended to overload the init
 method. See the documentation of the PeerGroup class being subclassed.

 <p/>FIXME: This is meaningless for the interface object;
 it is there only to satisfy the requirements of the
 interface that we implement. Ultimately, the API should define
 two levels of interfaces: one for the real service implementation
 and one for the interface object. Right now it feels a bit heavy
 to so that since the only different between the two would be
 init() and may-be getName().

<DD><DL>
<DT><B>Parameters:</B><DD><CODE>g</CODE> - The PeerGroup from which this Module can obtain services.
  If this module is a service, this is also the PeerGroup of which this
  module is a service.<DD><CODE>assignedID</CODE> - Identity of Module within group.
  modules can use it as a the root of their namespace to create
  names that are unique within the group but predictible by the
  same module on another peer. This is normaly the ModuleClassID
  which is also the name under which the module is known by other
  modules. For a group it is the PeerGroupID itself.
  The parameters of a service, in the Peer configuration, are indexed
  by the assignedID of that service, and a Service must publish its
  run-time parameters in the Peer Advertisement under its assigned ID.<DD><CODE>impl</CODE> - The implementation advertisement for this
  Module. It is permissible to pass null if no implementation
  advertisement is available. This may happen if the
  implementation was selected by explicit class name rather than
  by following an implementation advertisement. Modules are not
  required to support that style of loading, but if they do, then
  their documentation should mention it.</DL>

<DL>
<DD>Some Modules will wait for this method being invoked, before
 completing their initializatino to the point that they are fully
 functional. That is also the opportunity to supply arbitrary arguments
 (mostly to applications).
 
 <p/>If this module is a <A HREF="../../../../net/jxta/peergroup/PeerGroup.html" title="interface in net.jxta.peergroup"><CODE>PeerGroup</CODE></A> service, it may be invoked
 several times depending on its return value.

 it is ALWAYS ignored. By definition, the interface object
 protects the real object's start/stop methods from being called
