automatic Ridge regression

[MPenaR]

Hi, I've been testing your library, and using GroupLasso setting both l1_reg=0 and group_reg=0 I get a solution which I think is not the minimizer of L(beta,X,y) but the minimization of that times a high Ridge regression penalization.

Is this the expected behaviour?

I not interesting only in adding Lasso regularization but not including any kind of Ridge regression.

Thank you very much for your repo
