    Align equal-dimension and check-dimension more closely · ae9c9171

    1. Moved equal-dimension to physical-quantities.lisp.
    2. Add arguments errorp and zeros-have-any-dimension.
    3. Allow x or y to be a dimel and not only a pq.
    4. New function dimel-or-not.
    5. All three functions return a dimel if successful, or nil otherwise.
    6. All three functions take a pq, dimel, or other object as input; any other object is considered dimensionless.
    7. Possibly check-dimension and equal-dimension can be merged.
