#1570 Add medit format for the post processing
This will allow us to use ViZiR to visualize the output of the computations. This is useful for formulations where the shape function used for the unkowns are of degree higher (or lower) than 1. The expected format for the files is as follows for a scalar P0 unkown on a single triangle:
MeshVersionFormatted 3
Dimension 2
SolAtTriangles #Keyword among AtVertices, AtEdges...
1 #Nelements
1 1 #Nsolution (size of the global vector) #Ndimension for unknown (1 for scalar, 2 for a vectorial unkown in 2D)
2.0 #Value
