Including string as argument of MountPeriodicVectors. Now the table pair is printed on screen only if wished. It's desirable to use print and noPrint as usual strings, for clarity. However, print is the mandatory string to output the table.
In this commit, I renamed some variable arguments in Periodic with minor modifications; deleted sumIndexPBCPress... methods because they were redundant (now, only a method performs the operation for scalar quantities, whatever); added stepALEPBC() in Simulator to be independent of commenting lines. With this method, stepSLPBCFix() is uniquely called for the SL approximation.
Reinserting old MountPeriodicVectors to do tests. I could notice that the node indexing of the periodic is unbalanced when calling the method contractEdgesByLength(). Somehow, the structure of the nodes is changed and the periodic nodes start to pair with more than one. Removing this method, all the combinations for the mesh treatment based on the original version of risingBubble worked well. I didn't do the same complete test for the old version, but, at first glance, the problem occurrs too with that call.
