52 improve coverage two small things to fix (#56)
* improve cylinder tests * imporve point at function * delete temp mesh files * remove comment * rename cylinder test file * [compression cylinder] use tempfile and gmshio instead of meshio * attempt to make style check pass --------- Co-authored-by: Philipp Diercks <[email protected]>
