Change the function to test the Monge and inverse Monge characterization in order to avoid overflows
Add print matrix method for debug.
Add some new ways to create random Monge matrices. These functions are to be evaluated to ensure they are interesting for the tests.
Change generation method names.
Add a new way to generate Monge matrices. This one is a good one (at least for one of the envelope tree).
Add a benchmark criteria for envelope trees.
Bugfix: the print method did not print the last line and the last column of the matrix.
Bugfix: forgot to take the value instead of the pointer.
Bugfix: the query on the RMQ data structure has to be done on indices, not column position.
Fix bugs in the RMQ data structure implementation
Bugfix: take the right range when querying the RMQ.
