implemented rembo_lerot, added lerot implementation

-Added DBGD_paper.pdf
-Added the entire Lerot-implementation
-In lerot/src/scripts, you can find all relevant files for rembo_lerot.
It does not import any root-folder modules, so you can change those
around for rembo-bo if you want. All relevant stuff like
choose_bounded_region I simply copied in the lerot/src/scripts folder.

-rembo_lerot.py is the main script. Calling that will create a
Learning2Rank class instance. This class contais all methods for
interacting with Lerot.
- Everything is commented
- it is implemented exactly like the pseudocode I sent you two days ago
- your rembo-bo should still work since I didn't mess around with any of
the files there
-let me know if there is anything unclear
