 *  * CombinatorialClass has no documentation
 * It would be nice for CombinatorialObject to have a method 'indices' which returns a list of the index of *every* occurrence of x
 * Compositions has no option for allowing '0' parts (which are often useful)
 * Composition.conjugate() is not explained
 * Composition.descents() is not explained
 * Composition.major_index() doc-string says it is the sum of the descents. This is not true for the given example.
 * Composition.refinement() is not explained
 * SignedCompositions has no corresponding class SignedComposition
