Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Start changing the name of functions creating operators that are not types to lower case. E.g SecondDerivative->second_derivative

    boundary_restriction(grid::EquidistantGrid{1}, closure_stencil::Stencil, region::Region)

Creates the boundary restriction operator `e` as a `TensorMapping`

`e` is the restriction of a grid function to the boundary specified by `boundary` or `region` using some `closure_stencil`.
`e'` is the prolongation of a grid function on the boundary to the whole grid using the same `closure_stencil`.
On a one-dimensional `grid`, `e` is a `BoundaryOperator`. On a multi-dimensional `grid`, `e` is the inflation of
a `BoundaryOperator`. Also see the documentation of `SbpOperators.boundary_operator(...)` for more details.
