commit 27213d158e5ec4b606b4f4d0766bf75eeb18673f
Author: Richard Kreckel <kreckel at ginac.de>

    Tutorial: how to create noncommutative symbols?
    
    This seems to be frequently asked:

    Cherry-picked from dfaba64c.

commit 67ce3e7263c01ffa9d6df8d31d4d5506776f3bf7
Author: Richard Kreckel <kreckel at ginac.de>

    mul::can_make_flat(): Finish ancient unfinished code.
    
    This makes mul(expairseq({a*b,2},{b})) construct the canonical
    mul(expairseq({a,3},{b,2})). Normally, such term rewriting is done
    by the .eval() methods, but this is not done when a plain object of
    a class derived from basic is constructed.
    
    Cherry-picked from 26e2662e.

    unit_matrix(r,c) can return an evaluated matrix object.
    
    Cherry-picked from 052e9928.
