StitchBoundaryMeshGenerator

Description

StitchBoundaryMeshGenerator stitches two boundaries by merging their nodes together. The boundary ids are specified by stitch_boundaries_pair. To fully stitch two boundaries, the pairs of nodes on two boundaries must be at the same locations within a default tolerance. The two boundaries must be in the same mesh.
