Reorganize examples (#135)

* reorganize examples

* less AnalysisCallback output

* introduce sub-testsets to get a more detailed summary

* typo

* fmt

* re-use initial_condition_moist_bubble

* fix

* fix

* fix

* removed name from equations file

* change top level

* fix

* fix

* remove cartesian under euler, rename cartesian_manifold
