pROC Group Generic Functions
Redefine base groupGeneric functions to handle auc and ci objects properly on operations and mathematical operations.
Attributes are dropped so that the AUC/CI behaves as a numeric value/matrix, respectively.
In the case of AUC, all attributes are dropped, while in CI only the CI-specific attributes are, keeping those necessary for the matrices.
