Pathfinding using A*
Functions
| _M:calc (sx, sy, tx, ty, use_has_seen, heuristic, add_check) | Compute path from sx/sy to tx/ty | 
| _M:heuristicCloserPath (sx, sy, cx, cy, tx, ty) | The default heuristic for A*, tries to come close to the straight path | 
| _M:heuristicDistance (sx, sy, cx, cy, tx, ty) | The a simple heuristic for A*, using distance | 
| _M:init (map, actor) | Initializes Astar for a map and an actor | 
Functions
- _M:calc (sx, sy, tx, ty, use_has_seen, heuristic, add_check)
- 
Compute path from sx/sy to tx/ty
Parameters- sx: the start coord
- sy: the start coord
- tx: the end coord
- ty: the end coord
- use_has_seen: if true the astar wont consider non-has_seen grids
- heuristic:
- add_check:
 Return value:either nil if no path or a list of nodes in the form { {x=...,y=...}, {x=...,y=...}, ..., {x=tx,y=ty}}
