> Replace the LiteralConstraint we have at the moment (based on a big number of very specialized Evaluators that imply a lot of code duplication) with one that only uses MVEL to evaluate the constraints in the alpha nodes. As a second step add a counter on each of this constraints and optimize the ones that are invoked more frequently by jitting them with ASM
