#2797:

• Added IStochasticOperator interface to MultiPSOTopologyUpdater
• Changed parameter defaults to those described in the paper
• Added analyzer placeholder for the last iteration (has not been previously analyzed)
• Changed random topology initializer to include itself (to be able to use it with SPSOSwarmUpdater -> this should not change the old RealVectorSwarmUpdater)
• Changed ring topology initializer to include itself (same as above)
• Changed von neumann topology initializer to include itself (same as above)
• Added SPSO compatible random topology initializer (as described in the paper by Clerc)
• Changed sampling of the random directional vector to be uniformly random on the surface of a hypersphere to avoid a slight bias in diagonal direction
• Updating SwarmBestQuality and BestRealVector parameters in SPSOSwarmUpdater (an oversight)
• Added a faster method to create a copy of a RealVector (based on Array.Copy)
• Updated the sample
• Updated the sample's test results (due to changed sampling in SPSO2011ParticleUpdater)
