        + the number of static, lag, lead and both variables,
  + the lead_lag_incidence matrix for variables related to previous blocks
  + the index of reordered policy rule
for each block during the preprocessing step
- correct a bug in the comment related to first order derivatives in _dynamic.m file for a block decomposed model without bytcode
- avoid simplification of the Jacobian matrix (setting to zero all elements below the cutoff) for  estimated or stochastically simulated models: the cutoff option is set to 0.

      - Extends the algorithms compatible with bytecode to compute the  steady-state (ticket #11). The new values for solve_algo are:
   * 0: fsolve
   * 1: solve1
   * 2, 4: solve1 + block decomposition
   * 3: csolve
   * 5: LU decomposition with UMFPack (method handling sparse matrix in Matlab)
   * 6: GMRES
   * 7: BiCGStab
   * 8: bytecode own solver (use Gaussian elimination + sparse matrix)

- Bytecode can now evaluate a specific block instead of the overall blocks (new bytecode's option 'Block = block_number')

      Changes by Ferhat: · 0011678c
      sebastien authored 
      * fix options stack_solve_algo={2,3,4} (closes #68)
* fix crashes for singular normalizations (closes #44) and implement decreasing cutoff
* fail for stack_solve_algo=2 under Octave (because there is no gmres function in Octave)

      * In stochastic mode, now transforms the model by removing leads and lags greater or equal to 2 (creating auxiliary variables and equations in the process)
* Information about these variables is in structure M_.aux_vars
* Automatically add the necessary initialization for auxiliary vars after the initval block or load_params_and_steady_state

      * created a distinct expression tree for the static model (thus giving better sharing of sub-expressions and better computation of temporary terms for the static model)
* for that purpose, created StaticModel and DynamicModel classes (ModelTree still persists, but only contains code shared between StaticModel and DynamicModel)
* removed sparse static file (to be later replaced by new algorithm for steady state computation on large models)
