[src] Renamed the get_points_on_grid_pdf_ method per get_points_on_surface_grid_
Reworked the computation of points for easy maintenability : we get complete
loops ( (2j+1)^2 and (2j+1)^3 elements respectively in dimensions 2/3)
even if we get few elements. Maybe some optimization could be done using
symmeteries
The functions currently returns the indexes of edges/surfaces in order to use
the return list both for the computeEquivalentNormalPDFSum and
computeDeltaCharacteristicFunction methods
Ongoing work
[test] Updated elementary validation test : added graphical capabilities for better visualization. Need to perform later the 3D case
[src] Changed method and attribut names to conform the RandomMixture class
[src] Added computeLogCharacteristicFunction method. The computeCharacteristicFunction uses this last one
[src] Some cosmetics : fixed comments and updated repr method
