~~~ ~~~ [up] Subject: :cube feature

Ok, everybody wants a way to tell :CUBE "I have a cube like
so and so, solve it". The reason I have avoided doing this
(other than laze) is that you may specify a non-reachable
state. (Duplicate cubies, or purple faces, etc. are easy
to check for). I am not convinced that there is any
better or faster check for an inconsistent/unreachable
cube than trying to solve it and blowing out: lest
we find such a check (other possibility: run the program once
silently and once loudly; if the first time fails
(no, i will not make it list all cubes it cant solve)
give an error), all internal breakpoints become
user errors.

The second issue is what is the best language
to specify a configuration in? Comments?
