functions getDefaultClassifierNM1() and getDefaultClassifierNM2() allow to implicitly load the default classifiers when creating a ERFilter object
renamed getDefaultClassifierNM{1,2}() to loadClassifierNM{1,2}() and added "const std::string& filename" parameter (mandatory).
first parameter of createERFilterNM1/createERFilterNM2 is now mandatory. changed the sample program to use the new prototypes
