&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;One can ask a Module to stop.
  The Module cannot be forced to comply, but in the future
  we might be able to deny it access to anything after some timeout.

<DT><B>Parameters:</B><DD><CODE>group</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>implAdv</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.
