New description:
During SD10 in Nancy, Michael Brickenstein and I worked on making Plural
(the non-commutative extension of Singular) accessible from Sage.
The patches that resulted from this work are attached.
Newest functionality:
* coercion from basering/Integer types (still needs tests)
* flag to check degeneracy conditions on init
* relations for non-commutative rings
* most relevant functions for rings/polynomials/ideals (mostly adopted
from MPolynomialRing_libsingular/MPolynomialRing_libsingular/...)
e.g. std/twostd/syzygy_module/lc/lm/lt/monomial operations
* RingWrap and TermOrder were extended
* quick and dirty conversion of RingWrap to Sage rings (needs some care
as the resulting rings may not be unique and therefore may confuse
coercion)
* quotient of a non-commutative ring by a two-sided Groebner basis
* shortcut to create graded commutative algebras: SCA
They still need to be polished to be included in Sage.
Possible topics that need work are:
* put the files in sage/algebra/ ???
* make sure element does not export functions it doesn't support (e.g.
gcd)
For a full featured wrapper we also need the following (they should be
separated into different bugs once this one is done):
* groebner basis
* predefined structures from the library
