Comment (by jhpalmieri):
You should make sure to provide an interface to
`simplicial_complexes.ChessboardComplex(r,s)`: your `Board` class could
have a `simplicial_complex` method (or something similar) which returns
the complex. Actually, you could do this:
{{{
#!python
def _simplicial_(self):
"""
Return simplicial complex version of ...
"""
from sage.homology.examples import simplicial_complexes
return simplicial_complexes.ChessboardComplex(self.r, self.s) #
or whatever
simplicial_complex = _simplicial_
}}}
The point behind having a `_simplicial_` method is that if `B` is an
instance of the `Board` class, you can then call `SimplicialComplex(B)`
and it will call this method.
You also might be able to improve the implementation of the
`ChessboardComplex` or the `matching` function in the same file, and that
would be greatly appreciated.
