`CoordinateSystem` differed from `Field` in that its `GetData` method returned an `ArrayHandleVirtualCoordinates` instead of a `VariantArrayHandle`. This is probably confusing since `CoordianteSystem` inherits `Field` and has a pretty dramatic difference in this behavior. In preparation to deprecate `ArrayHandleVirtualCoordinates`, this changes `CoordiantSystem` to be much more like `Field`. (In the future, we may change the `CoordinateSystem` to point to a `Field` rather than be a special `Field`.) A method named `GetDataAsMultiplexer` has been added to `CoordinateSystem`. This method allows you to get data from `CoordinateSystem` as a single array type without worrying about creating functors to handle different types and without needing virtual methods.
