…racters This was suggested by Gabi Nebe. Note that just a few weeks ago, these functions became documented for vector spaces (see gap-system#4339).

This is triggered by a discussion with @AnnaKDS and @wucas.
They've been around for many years but undocumented; people still use them. I see no harm in documenting them.
Related: issue #1362 which discusses a
SymmetricPowermethod for matrices, which perhaps also should be documented? And related to that (as well asTensorProduct) there isKroneckerProduct, which already is in the manual -- but perhaps there should be references between those?In the same issue, problems with these over finite fields are mentioned. Perhaps those should be investigated and fixed.
Finally, some tests in the test suite for these would be nice.
