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.
