------------------------------+---------------------------------
Currently the Matroid class does not provide oriented matroids.
I propose to implement a base class oriented matroids, that provides:
- the usual basic functions, like rank etc.
- a representation of the chirotope functions
- checking if it is uniform
- giving out the face lattice
- ...
This could then for example be used to add an appropriate function to the
Polyhedron class.
