Progress: Continue re-designing of the memory logic.

Progress: Continue re-designing of the memory logic.

I would note that I am leaving the append() and append_all() for the IKI structures because they are complex.
In the long term I may end up adding back the append() and append_all() functions for each type.
At this time it is more advantageous for me to not have that consistency for easier maintainability while the project is evolving and refactoring.

I still need to look over the string and UTF string memory related functionality.
This will be more delicate and given the size of these two projects will be a bit time consuming.
