Inserting set(Un)StretchJetMesh to perform the geometrical transform over the mesh. According Norberto's idea, the mesh transform by stretsching must be corrected before entering in the ALE operations. Thus, the finiteelement calculations are done in a background/abstract mesh and the ALE operations in the real mesh. Such transform delude the mesh generator, which would launch error when getting a messy and modified mesh.
Adding initThreeBubbles as Rabello's remarks.
Inserting new version of {insert}remove3dPointsByDiffusion from Rabello's standardversion.
