New description:
new functionality for the composition constructor:
- construct a composition from a subset
new functionality for compositions:
- parent -- returns Compositions()
- reversed - reverses
- refinement_splitting
- refinement_splitting_lengths
- deprecated refinement in favour of refinement_splitting_lengths
- partial_sums(self, final=True):
- to_subset(self, final=False):
- to_partition(self):
- shuffle_product(self, other, overlap=False):
new functionality for the set of all compositions:
- put it in the category of {{{InfiniteEnumeratedSets}}}
- subset method to extract subsets of composition (by size)
