  - [x] Remove grid as a property of the Laplace tensor operator
  - [ ] Update how dependencies are handled for tests. This was updated in Julia v1.2 and would allow us to use test specific dev packages.
 
-## Reasearch and thinking
- - [ ] Use a trait to indicate if a TensorMapping uses indices with regions.
-    The default should be that they do NOT.
-        - [ ] What to name this trait? Can we call it IndexStyle but not export it to avoid conflicts with Base.IndexStyle?
- - [ ] Use a trait to indicate that a TensorMapping har the same range and domain?
- - [ ] Rename all the Tensor stuff to just LazyOperator, LazyApplication and so on?
- - [ ] Figure out repeated application of regioned TensorMappings. Maybe an instance of a tensor mapping needs to know the exact size of the range and domain for this to work?
- - [ ] Check how the native julia doc generator works
-    - [ ] Check if Vidars design docs fit in there
- - [ ] Formalize how range_size() and domain_size() are supposed to work in TensorMappings where dim(domain) != dim(range) (add tests or document)
- - [ ] Create a macro @lazy which replaces a binary op (+,-) by its lazy equivalent? Would be a neat way to indicate which evaluations are lazy without cluttering/confusing with special characters.
- - [ ] Specificera operatorer i TOML eller något liknande?
- - [x] Redo all Tensor applys to take Vararg instead of tuple of Index?
- - [x] Should there be some kind of collection struct for SBP operators (as TensorOperators), providing easy access to all parts (D2, e, d , -> YES!
- H.. H_gamma etc.)
- - [x] Is "missing" a good value for unknown dimension sizes (of `e*g` for example)

 # Wrap up task
 
  - [ ] Kolla att vi har @inbounds och @propagate_inbounds på rätt ställen
