* This class is able to discreatize on a Matrix any operator. In order to create a consistent
* Matrix it is required that each processor must contain a contiguois range on grid points without
* hole. In order to ensure this, each processor produce a contiguos local labelling of its local
* points. Each processor also add an offset equal to the number of local
* points of the processors with id smaller than him, to produce a global and non overlapping
* labelling. An example is shown in the figures down, here we have
