Allow (S)EP with arbitrary sequence of innovations.
...
The third input argument of extended_path Matlab/Octave's routine is the
sequence of shocks (T*n array, where n is the number of exogenous
variables and T is the size of the sample). If the third argument is
empty, the (stochastic) extended path is run with gaussian
innovations (this corresponds to the previous behaviour).
TODO:
- Fix the compatibility with ep.replic_nbr
- Check the 'calibrated' mode.

Transposed the definition of the innovations in (stochastic) extended path routine, so that, for a given state of the random number generator, stochastic simulations obtained with extended_path and stoch_simul commands consider the same innovations (when the number of shocks is greater than one). Otherwise the stochastic simulations cannot be compared.

* Removed the necessity (for the user) to run stoch_simul bebore
executing the exetended path routine (when options_.init>0).
* The value of options_.ep.init defines the mix (used for the
initialization of the perfect foresight solver) between the previous
perfect foresight solution and the path obtained with an order one
perturbation approach.
* Removed timing related statements.
* Changed homotopy set-up for stochastic extended path: add future
multivariate innovations one by one.
* Endogeneously increase step_length in the homotopy routine.
* Removed homotopy_2 related code.
