- fail when user tries to initialize a variable at a period which is not in the model, and make the error message explicit
- correctly handle exogenous variables in stochastic mode, which are also substituted with an aux var
- added test files

Preprocessor: fix possible bug in histval (need to limit search of aux vars to aux vars for lagged vars, otherwise we could have a wrong match with some other kind)

This reverts commit 524e9a9c.

lagged endo/exo so that they contain the type-specific symbol ID (instead of
the preprocessor internal symbol ID)

* give the possibility of calibrating measurement errors in the "shocks" blocks (only for observed endogenous variables)
* M_.H is now initialized in the preprocessor
* only one "varobs" statement is now accepted in a MOD file

Beautified preprocessor code (uncrustify + emacs + manual adjustments, in particular with templates in MacroValue)

preprocessor:
* add a field "M_.orig_endo_nbr" containing the nbr of endogenous before adding aux vars
* always provide "M_.aux_vars" (define it to "[]" when there is no aux var)
* rename "M_.aux_vars().orig_endo_index" to "M_.aux_vars().orig_index"

M-files:
* for commands which accept a list of variables (stoch_simul, osr, estimation, dynasave, dynatype, datatomfile), when no variable is given, use only the set of original endogenous (without aux vars) as the default
* when displaying the decision rule, when there is aux vars in the state variables, replace them by their original name (with the right lag)
* in "steady", don't display aux vars
* special exception for ramsey policy: all vars (including aux vars) are displayed, because the system of aux vars from ramsey policy is not compatible with the aux vars from the preprocessor

* fixed a bug with EXPECTATION operator: now handle model local variables
* substitute EXPECTATION operator even in deterministic models (for avoiding crashes, even if use of this operator doesn't make sense there)
* forbid the use of EXPECTATION and STEADY_STEATE outside model block
* minor implementation changes in EXPECTATION and STEADY_STATE operators

reference manual:
* documented EXPECTATION and STEADY_STATE operators
* added a note in write_latex_{static,dynamic}_model commands documentation about auxiliary variables and other model transformations

* reworked a little bit the implementation
* documented the command in the reference manual
* added a test

* fixed substitution of endogenous with leads >= 2: take into account exogenous with leads in non-linear terms
* fixed substitution of exogenous with leads: take into account other variables with leads in non-linear terms

* 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

trunk preprocessor: added new statements "write_latex_dynamic_model" and "write_latex_static_model" which list model equations in LaTeX code


git-svn-id: https://www.dynare.org/svn/dynare/trunk@2654 ac1d8469-bf42-47a9-8791-bf33cf982152

* reorganized symbol table so that internally symbols have a unique integer ID (as a result, sparse code is temporarily in a broken state)
* rewritten from scratch ModFile::evalAllExpressions()
* {load,save}_params_and_steady_state moved to NumericalInitialization.{cc,hh}
* fixed bug related to endval block

* used SVN changelog to determine first copyright year
* used 2003 if file present from the creation of SVN repository

v4 parser: removed the mechanism which records whether a given symbol has been referenced or not in the model block (useless and creates problems for standalone BVAR estimation)

* renamed "local parameters" to model local variables (eModelLocalVariables)

* reshaped DataTree/ModelTree using a more object-oriented approach
* improved expression sharing algorithm (temporary terms in output files), resulting in smaller output files for big models
* optimized performance (both in computing time and memory consumption)
* bugfix: the expressions stored in local parameters of models (pound expressions) are now derived
* bugfix: cosh(0) = 1
* removed some useless parentheses in output
