Removed asList method from topologies since a topology is already a list.
Removed unused update method in topologies.
Refactored LBest, Gbest and Hypercube topologies, where GBest and LBest are special cases of LBest.
Fixed up von Neumann topology code layout.
Simplified Von Neumann topology implementation.
Refactored topologies to extend AbstractTopology only. The different topologies now only deal with the neighbourhood iterator and neighbourhood sizes, AbstractTopology does the rest.
Moved getBestEntity to static methods in Topologies. Also added getNeighbourhoodBest methods
Minor fixes to javadocs and logic errors. Added TopologiesTest.
Removed NaturalOrderFitnessComparator which had the same implementation as AscendingFitnessComparator.

    Update ControlParameter usage.

    The patch had a few places where the ConstantControlParameter was created
    using a new. Changed to use the factory method.
