Need a formatting function for EvaluationResults #57

def shex_results_as_string(rslts: EvaluationResult) -> str:
    """ Pretty print ShEx Evaluation result """
    # TODO: Add this method to ShEx itself
    rval = [f"Evalutating: {str(rslts.focus)} against {str(rslts.start)}"]
    if rslts.result:
        rval.append("Result: CONFORMS")
    else:
        rval.append("Result: NonConforming")
    rval += rslts.reason.split('\n')
    return '\n'.join(rval)
