Hi, I will now also have time to help in this area.
I had a look at your changes in the MVRTreeMap.RTreeCursor class (method min). I wrote a (somewhat randomized) test case but couldn't get the original code to fail so far. I think I understand your changes, but I believe that there should be a simpler solution... With a good test case that should be relatively easier to achieve. About support for "&&", and possibly other new operators: I think it's best to just hardcode those in the parser. I don't think it's important to allow custom operators in applications. I wonder what the possible operators are, and what is the operator precedence.
