Progress: Continue working on completing the remove program.

Update to the latest FLL changes.
The FLL changes include parameter processing changes to support the `--` parameter as a stop processing parameters option.
Enable this and remove the manual process that was previously performed.

Add the root path check.
Make sure a parameter exists in the `remove` program to toggle this behavior.

A lot of the simulate and directory recursion behavior is now dead code due to the recent recursion changes.
Remove the dead code and simplify the parameters.

Update the unit tests.
I noticed some situations in the unit tests that could be improved to be more accurate and correct.
An `@fixme` has been added to accomplish this.
