Before, `ArrayExtractComponent` only worked with `Vec` types. Anything that was not specifically a `Vec` was assumed to be a basic component even if it had `VecTraits`. This was changed to extract components out of anything that has `VecTraits`. The assumption is that all components of the Vec-like object are packed tightly in the object. This allows `ArrayExtractComponent` to work with objects like `vtkm::Range` and `vtkm::Bounds` and extract their parts as expected.
