The original implementation doesn't provide the model saving function, so it resets "param_method" from ALS to MCMC. Here I add an additional flag to enable the saving function for ALS.
Thanks for the great feedbacks. Exiting libfm indeed avoids the overlook issue. In addition, I added the removeParameter function as well. I think maybe it is useful for other follow-up tasks.
