instantDrag for Maya

I got a request about a function call rePosition in rapidPlace,
which allow user to simply click and drag mesh on another surface.
unfortunately, it was only working on the mesh placed by rapidPlace tool.
so I think it will be a useful tool if it can work in any situation.
no mesh pre-select is required, once the tool is activated, just simply click and drag on any mesh which is on top of another surface.
eg:
mesh with transform,
mesh inside groups, those groups may also have transformed,
pivot point not in the centre of mesh
mesh already been frozen in transform
mesh under mesh
also, add hotKey for quick adjustment
## hotKey :
## + Ctrl ---- rotate
## + Shift & Ctrl ---- scale
## + Shift ---- duplicate current mesh
## + Alt ---- snap to face center or vertex
## + Alt & Shilt ---- force center pivot and snap mesh to surface

let me know what you think, and happy to hear any suggestions to make the tool simple but more functional.
