Forbid copying an Algorithm_Factory; could easily cause double-delete,
especially in a multithreaded environment, and doesn't seem like a
useful operation to support.
(In principle, we could support this by adding a clone() call to
Algorithm_Cache, which would in turn call clone on each of it's held
prototype objects, plus adding a clone to Engine. Doesn't seem worth the
bother, though.
