Comment:
Some comments:
- Do we want these to be axioms since these properties for subcategories
do not make as much sense (e.g., for groups, L-trivial = R-trivial =
J-trivial = category consisting only of the trivial group, correct?)
- Typo "preoder".
- Do we want to spend some time trying to beautiful axiom printing (i.e.,
"J-trivial" instead of "jtrivial")?
- I would like to see the defining properties to the category level
documentation, not only in the subcategory methods.
