// This application/dictionary controls:
// - optional: create new patches from boundary faces (either given as
// a set of patches or as a faceSet)
// - always: order faces on coupled patches such that they are opposite. This
// is done for all coupled faces, not just for any patches created.
// - optional: synchronise points on coupled patches.
// Do a synchronisation of coupled points.
// 1. Create cyclic:
// - specify where the faces should come from
// - specify the type of cyclic. If a rotational specify the rotationAxis
// and centre to make matching easier
// - pointSync true to guarantee points to line up.
// 2. Correct incorrect cyclic:
// This will usually fail upon loading:
// "face 0 area does not match neighbour 2 by 0.0100005%"
// " -- possible face ordering problem."
// - change patch type from 'cyclic' to 'patch' in the polyMesh/boundary file.
// - loosen match tolerance to get case to load
// - regenerate cyclic as above
// Tolerance used in matching faces. Absolute tolerance is span of
// face times this factor. To load incorrectly matches meshes set this
