The main method of Main class takes two txt files as input and compare the methods listed in these two files;
Then it will figure out which methods shown in these two files have same method name and return type, and in the final step, it will generate a list of entries in the form "method signature for JavaMOP; line number for JavaMOP method; method signature for RV-Monitor, line number for RV-Monitor method", where the methods of javamop and rv-monitor in the same entry have the same return type, method name and args.
The resulting html file is expected to facilate the refactoring work of JavaMOP, and removing the duplicate part in JavaMOP which has already been defined in RV-Monitor.
