Fixing topology related interface/class tree

- (Mutable)Topology no longer implements ImmutableTopology

    --- BaseTopology (was ImmutableTopology)
     |
     +-- ImmutableTopology (new)
     |
     +-- MutableTopology (was Topology)
       |
       +-- RefreshableTopology
       |
       +-- TopologyInternal
            This interface is placed in wrong place. To be fixed later.
