* use elementwise size in node vertex consistency check

* add comment explaining maximum(..., 1)

* use test based on maximum absolute vertex coordinate instead of element size, and add tests

* assume absolute and relative tolerances are the same for now

* add test for false negatives

* zero-size -> zero-D

* improve vertex consistency check error message

* use a specific exception type for consistency check

* improve tests

* just use relative tolerance and skip dim==0 case

* only do consistency check in debug run

* Reenable 0D tests, remove 1e-5 crit tol scaling, take into account abs tol in node-vert-consistency test tests

* remove return_sets option from get_partition_by_pymetis

* fix bugs in MPIBoundaryCommSetupHelper

* flake8

* fix bug

* add a couple of fixmes

* handle groupless mesh case in dim/ambient_dim

* Revert "handle groupless mesh case in dim/ambient_dim"

not a good solution

* disable removal of empty mesh groups in partitioning

* fix some issues with partitioning docs

* remove empty-group filtering

* clarify part vs. partition terminology

* change some asserts to exceptions

* add a couple of FIXMEs

* cosmetic change

* detect elements that belong to multiple parts

* add return_parts argument to partition_mesh

* add type hints to mesh partitioning

* Fix some annotations in mesh.processing
