+regularized maximum likelihood.  Next to the fitting procedure, following
+functionality is available:

+Selection of the regularization tuning parameter lambda using three different
+approaches: in-sample, out-of-sample or using cross-validation.
+@item
+S3 methods to handle the fitted object including visualization of the 
coefficients
+and a model summary.
