Added a new input argument (epsilon) in gradient routines and csminwel.m. This parameter defines the length of the steps considered
...
by numgrad routines to compute the gradient. The default value (defined in global_initialization.m) for this parameter is 1e-6. The
value of epsilon is stored in options_.gradient_epsilon.

* Efficiency change in numgrad (two, three and five points formulas) files. Do not evaluate the objective function at x, this is already

done in csminwel.m or in csminit.m.
* Fixed bug in the calling sequence of numgrad5.m (five points formula) in csminwel.m.
* Cosmetic changes.

* Changed numgrad.m. If fcn(x+h) is not well defined (for instance cost_flag=0 because of BK conditions) we compute the gradient using (fcn(x)-fcn(x-h))/h instead of the original formula (fcn(x+h)-fcn(x))/h.
...
* Added function numgrad3.m. This new function uses a three point formula to compute the gradient. By default Dynare uses the two point formula. By setting options_.gradient_method=3 Dynare switches to the three point formula. Note that an input argument has been added to csminwel.
* Added automatic detection of needed constant in dsge-var model (may be problematic is some cases)
