Previously, DynamicArrayHandle and DynamicCellSet had slightly different interfaces to their CastTo feature. It was a bit confusing and not all that easy to use. This change simplifies and unifies them by making each class have a single CopyTo method that takes a reference to a cast object (an ArrayHandle or CellSet, respectively) and fills that object with the data contained if the cast is successfull. This interface gets around having to declare strange types. Each object also has a Cast method that has to have a template parameter specified and returns a reference of that type (if possible). In addition, the old behavior is preserved for DynamicArrayHandle (but not DynamicCellSet). To avoid confusion, the name of that cast method is CastToTypeStorage. However, the method was chaned to not take parameters to make it consistent with the other Cast method. Also, the IsType methods have been modified to reflect changes in cast/copy. IsType now no longer takes arguments. However, an alternate IsSameType does the same thing but does take an argument.
