Added a cherry-pick routine.
Extracts equations from a mod file and produce .inc files (equations, lists of parameters, endogenous variables and exogenous variables) that can be included in a mod file that will be used to simulate the model. If an innovation has a tag `(used='estimationonly')` it will be excluded from the generated files (ie list of shocks and equations).time-shift

% INPUTS
|

% - infile [string] Name of the mod file where all the equations used for estimation are available.
|

% - outfold [string] Name of the folder where the generated files are saveda subset of the equations is to be printed.
|

% - eqtags [cell] Equation tags of the selected equations.
|

%
|

% SPECIAL REQUIREMENTS
|
