Sébastien Villemot ed2f6d62c1 Refactor code for collecting variables appearing in expressions
- rename ExprNode::collectVariables in ExprNode::collectDynamicVariables
- new ExprNode::collectVariables: same as above, but without lag information
- remove ExprNode::findUnusedEndogenous: essentially redundant with the above)
- remove ExprNode::collectModelLocalVariables: idem

integer power arguments   to insure that they are positive

variables and probably violates Jensen inequality in some cases.

Ferhat Mihoubi 0a3c8a4b0c - compute the jacobian matrix for exogenous, det_exogenous and previous blocks endogenous
- preprocessor provides informations about the dynamic structure of each block

- bytecode can be used to evaluate a model
