glm2 bug fix. There were two bugs regarding computation of lambda sequence:
a) the L2 penalty accumulated on the matrix over different lambdas
b) setting rho (constant used by our ADMM elastic net solver) as a constant to 1e-5 does not work for large lambda values (did not really test those before), rho being to low meant our ADMMSolver did not  converge (by far!) leaving all values as 0s. Now rho is set as 0.1 lambda.
LSM ADMM solver: set rho as 0.1*alpha*lambda instead of 0.1*lambda.
