Add pop front/back methods to hybrid path
Summary
Add pop_back
and pop_front
methods to HybridTypeTree
.
Discussion
- Both methods are possible to be
constexpr
as long as core/dune-common!996 (merged) is accepted.- Question: does this code needs to be fully compatible with dune 2.8 or do we just look forward? Making it compatible is easy, is just a question of how clean do we want the code.
- I modified asserts to use the dune test suite since these tests are run in release mode anyways.
- To my knowledge, these are the only two methods we need in PDELab to finally move everything to
HybridTreePath
and stop supportingTreePath
.
