FEVDs for "sep Q" models
FEVDsep(ModelType, ModelPara, FEVDhoriz, FactorLabels, Economies)
string-vector containing the label of the model to be estimated
list of model parameter estimates (see the "Optimization" function)
single numerical vector conataining the desired horizon of analysis for the FEVDs
string-list based which contains all the labels of all the variables present in the model
string-vector containing the names of the economies which are part of the economic system
Structural shocks are identified via Cholesky decomposition
