Liking cljdoc? Tell your friends :D

Little a* pathfinder for 2D binary grids. Diagonals are punished, and distance estimation is performed by default using the manhattan heuristic.

**lein:**

```
[clj-tiny-astar "0.1.1-SNAPSHOT"]
```

**Usage:**

Clone into a local repository and:

```
;; this is designed to operate on bounded grids
(clj-tiny-astar/a*
[4 4] ;;bounds of the grid (width & height)
my-predicate ;;predicate that takes a point [x y] and returns whether a cell is walkable
[0 0] ;;from
[3 3] ;;to)
;;example result, diagonals are punished:
[[0 0] [1 1] [2 2] [3 3]]
```

the predicate function takes a point (tuple of x and y).
