VTK-m ArrayHandle can now take ownership of a user allocated memory location
Previously memory that was allocated outside of VTK-m was impossible to transfer to VTK-m as we didn't know how to free it. By extending the ArrayHandle constructors to support a Storage object that is being moved, we can clearly express that the ArrayHandle now owns memory it didn't allocate.
Here is an example of how this is done:
T* buffer = new T[100];
auto user_free_function = [](void* ptr) { delete[] static_cast<T*>(ptr); };
vtkm::cont::internal::Storage<T, vtkm::cont::StorageTagBasic>
storage(buffer, 100, user_free_function);
vtkm::cont::ArrayHandle<T> arrayHandle(std::move(storage));
