Create subField from existing Field
Add functionality to create a subField
from an existing field containing a subview of the field data stored in BareField.dview_m
. It should create a reference to a subview of the data, so as not to force a deep_copy()
.
This is only useful, if the changes made in the subField
should be reflected in the original field (same behavior as with Kokkos::subview()
).
