New description:
The new aim of this ticket is to add an interface to the
[http://www.singular.uni-kl.de/Manual/latest/sing_427.htm#SEC480
letterplace] component of Singular, namely providing
* A new implementation of free algebras with fast arithmetic.
* Degree-wise Gröbner basis computation for twosided homogeneous ideals
of free algebras.
* Normal form computation with respect to such ideals.
and in addition
* One- and twosided ideals of noncommutative rings.
* Quotient rings of such ideals
(Note that the original purpose was merely to compute Groebner bases up to
a degree bound of two-sided ideals of free algebras, but without normal
form computation etc.)
Examples are below, in the comments.

Comment:
Replying to [comment:44 SimonKing]:
> I just found that the documentation (at least with #9976 applied) is not
good. Some stuff is included that certainly does not belong there.
Actually, on second thought, it belongs there: I am talking about the two
singular_function instances included in the module. The main problem was
that singular_function includes the documentation provided by Singular
without taking care of formatting -- resulting in numerous errors (e.g.,
back ticks are misinterpreted as the beginning of Latex expressions, the
indentation is handled differently, and so on).
In #11268, I suggest to take care if it by turning the Singular
documentation into a verbose code block. With that change, the
documentation looks a lot better. I therefore make it a new dependency.
Depends on #11068 #11268
