Progress: Continue working on completing the remove program.

This wraps up most of the `remove` program functionality.
It seems that I already had Time and EpochTime logic in place and I didn't have to do anything.
Add the program unit tests for time and EpochTime.

Fix some documentation comments in the program unit tests.

There is a remaining `@todo` in the `remove` program that will need to be address in the FLL.
I will have to brain storm on how I want to do this and I may end up adding callbacks to all file read and write functions.
