-    boundary_operator(grid,closure_stencil,boundary)
-
-Creates a boundary operator on a `Dim`-dimensional grid for the
-specified `boundary`. The action of the operator is determined by `closure_stencil`.
-
-When `Dim=1`, the corresponding `BoundaryOperator` tensor mapping is returned.
-When `Dim>1`, the `BoundaryOperator` `op` is inflated by the outer product
-of `IdentityTensors` in orthogonal coordinate directions, e.g for `Dim=3`,
-the boundary restriction operator in the y-direction direction is `Ix⊗op⊗Iz`.
