Casting to unified parameters works for RBFN
Documentation of members
Merge branch 'master' into model_parameter_unified
IMplemented for LWR
IMplemented for LWPR
IMplemented for GPR
All model parameters (except IRFRLS) can be converted to  ModelParametersUnified (compiles, but not tested yet)
Unified model works for RBFN and LWR
GMR also works now
Supress output. Casting to UnifiedModelParameters works for LWR, GPR, GMR, RBFN now. IRFRLS and LWPR still to do.
