Dynamic Retaining Walls

Now this could be interperted as retaining walls which are created dynamically durring terrain designations, that's not what this is. Rather it seeks to overhaul how building retaining walls works entirely. Replacing the "blocks" we have currently, with a node based, dragable system, similar to railroads. Which allows for more granular heights, sloped walls (to follow sloped terrain designations), simpler merging of walls, and options for half tile (current width) or full tile walls. For each 5 elevation steps up, the base of the wall increases by 1/2 a tile for half tile walls, and 1 tile for full tile walls, the swalls should also be directional, with the outer wall "leaning" towards the inner wall. Overall I think such a system could be more user friendly for new players than the current individual wall segment(s) we have now, and could provide a cleaner asthetic, potentiallw allowing for additional wall materials too, to match surface designations.
