// To add new Similarity measures the following steps have to be done
// 1: Create the Class
// 2: Create the similarityRepresentation for the class
// 3: Add the similarity measure to the config::Sim_Measures enum
// 4: In ReaderParser add the measure to the Constructor
// 5: In the responsible Parsers, add the template instantiation
// This can most probably be simplified by c++ magic
