added md files

I have a problem with hyper link that I could not resolve in PythonVsJava.md It's no fun to work with Hebrew and md. The markdown tools Udi suggested do not support rtl. I ended up using ipython notebook plus https://github.com/ronenabr/ipython_bidi_markdown than saving it as notebook file and converting to md and than some more editing in notepad++ (convert adds an empty line at the beginning of the file which messes the meta data). and than some more editing for solving problems I saw on the server. the character are not were you see them in notepad and you end up guessing where the characters you wish to edit. If you know of a better solution...
