Progress: controller program and related.

Use "copy" instead of "clone", it seems more accurate given that the code is not guaranteeing the same exact memory structure (only the data is guaranteed).
I believe that I need to document my "completeness principle", documenting the structures and what needs to be done.
I also need to document the exception cases.

Implementing the rule copy function, I realized that I need to have the copy function and not just utilize the "append" functions.
There are many functions where "append" does not make sense.
This means that "copy" must be part of the completeness.

Comment out the cache clearing code.
I will probably get to that part last.
