Merge request for BR(Lb2dsp) analysis
Added HILLdini plus HORNSdini function, made weighted fit possible and created better compatibility for Lb2LcPi and Lb2Dsp. Also updated config files for Lb2Dsp analysis and renamed folder containing config files. @adudziak Can you double-check me? Especially the parts in MassFitUtils.cxx, since typos here can be quite bad.
