Message:

#1628

• Updated branch from trunk
• Changed ReferenceEqualityComparer<T> to become a non-generic class (generic implementation probably was only made because of lacking support for co- and contravariance in C# 3.5)
• Added finished experiment from sample algorithms to the tests
• Wrote a unit test to instantiate every IDeepCloneable type, clone it and compare the objects in the object graph for equal references
• Wrote a unit test to load the experiment, clone it and compare again the objects in the object graph
• Preliminary fix for a potential bug in ThreadSafeLog
• Preliminary fix for a potential bug in OperatorGraphVisualizationInfo
• Preliminary fix for a potential bug in Calculator (and added license headers)
• Preliminary fix for a potential bug in ScrambleMove
