Parses a QChem output file with multiple calculations
            1.) Seperates the output into sub-files
                e.g. qcout -> qcout.0, qcout.1, qcout.2 ... qcout.N
                a.) Find delimeter for multiple calcualtions
                b.) Make seperate output sub-files
            2.) Creates seperate QCCalcs for each one from the sub-files
