compute_Obs_CGO() added. It requires a Model.conf file to initiate and reads the list of observables and CGO from the Model.conf file. This is done to not complicate the input of the correlation matrix. All other methods remain the same with minor modifications for error handling.
Example main for using ComputeObservable::compute_Obs_CGO().
Minor bug removed.
Cosmetic changes.
Configuration file changed to include example main that has been added.
