RootRework: Move_smooth merge

[MoffKalast]

The move_smooth version of move_basic should get separated and moved back here as a branch (as a start) and then merged to become the main version later down the line once the rest of the issues are sorted out..

[JanezCim]

@mbostic and @JanJericevic look at move_basic and try to generate list of questions for @tp4348

goal: understand flow of program, precursor to actually working on merging.
