public Interface MountPlugin

This interface can be optionally implemented by a DataPlugin or ExecPlugin in order to get information about its absolute mount points in the overall DMT.

This is especially interesting, if the plugin is mapped to the tree as part of a list. In such a case the id for this particular data plugin is determined by the DmtAdmin after the registration of the plugin and therefore unknown to the plugin in advance.

This is not a service interface, the Data or Exec Plugin does not also have to register this interface as a service, the Dmt Admin should use an instanceof to detect that a Plugin is also a Mount Plugin.
