v1.3: LCEN: a new variable selection algorithm for nonlinear, interpretable models
Created LCEN, a variable selection algorithm used with the expanded feature set of (D)ALVEN to create nonlinear, interpretable ML models. This new algorithm is much better at selecting the correct variables, ignoring irrelevant variables, and producing models with lower errors and greater stability.
Also added new examples that better highlight how to use SPA.
