We implement graded algebras with maximal finite degree. That is, each generator has a integer degree, and multiplications exceeding a fixed degree yield zero.
This implementation is for example us…

Add functionality so that we can compute a basis for (co)homology in dimension n of a chain complex C_* in terms of a given basis for C_n.

We add methods to check if a given order of facets is a shelling order and for calculating restricted sets (when shellable). This also adds code to construct the f-triangle and h-triangles (to use …

Sage now contains various lines of the form `from builtins import ...` which is provided by the `future` package.
Currently, `pyparsing` is needed for `src/sage/homology/simplicial_set_examples.py`…
