Multipatch geometry tests

This folder contains sub-folders to group tests for operators that only work on multi-patch geometries. The folders are:

• connectivity : Contains tests of operators and tags which describe how patches are connected.
• geometries : Contains geometries that can be used in other folders to test functionalities.
• interface_derivatives : Contains tests for the interface derivative computation operators.
• spline : Contains tests of multi-atch spline operators.
