Get rid of entirely of Felisce ordering. Up to now, I had to resort to a dirty trick to make HappyHeart work: there was a conversion tool that gave the position in the vector of Felisce of a given geometric element. So I had to deal with 'HappyHeart ordering''and 'Felisce ordering', which was very clumsy. Now this tool has been removed, which was not easy to do: the algorithm worked in Felisce because many loops made strong assumptions on the order in the vector; for instance a quantity that should be the same (say the position in a local mesh of a geometric element) was calculated completely outside of the local mesh; it worked because some loops happen to fill the vector the same way GeometricMeshRegion did!
