Old description:
> Patch adds a routine to create a matrix with every entry equal to one.
New description:
This ticket began with building an all-ones matrix constructor, as
contained on the first patch. But that was already happening over on
#9685.
New title, new decription, new patch are about adding onto the
`ones_matrix` constructor. Specifically,
1. Significant additions to the documentation.
2. Setting {{{nrows=None}}} in the function definition allows for a call
with just a single integer entry, producing a square matrix over the
integers, similar to the behavior for `identity_matrix`. Requires one new
error-check.
3. Isn't it better to coerce a generic 1 into the ring and then use that
to populate the matrix? I've done that.
