add computation of error on dual problem and change a little CRB::run interface ( more information given )
(minor) adapt to new CRB::run interface
add function that reads parameters on a file and build associated sampling with closest parameters in the supersampling
add option to use parameters selected during the SCM offline step
add option to test SCM on parameters selected during the offline step
give the possibility to use predefined parameters for the sampling M_C ( offline step )
