parse-grid-bench
================
Parses the data files from Nathan Sturtevant's grid path finding benchmark.

Example

``javascript
var fs = require('fs')
var path = require('path')
var imshow = require('ndarray-imshow')
var parseMap = require('../map')
var parseScen = require('../scenario')

//Read in data
var mapStr = fs.readFileSync('./maps/bg512/AR0011SR.map', 'utf-8')
var scenStr = fs.readFileSync('./scenarios/bg512/AR0011SR.map.scen', 'utf-8')

console.log(parseScen(scenStr))
imshow(parseMap(mapStr))
`

API

#### var map = require('parse-grid-bench/map')(mapStr)
Parses a map file from a string

* mapStr is a string containing the map data

Returns An ndarray representing the map data. Each entry in the map file has the following meaning:

* 0 free terrain
* 1 impassable terrain/obstacle
* 2 swamp
* 3 water

#### var scen = require('parse-grid-bench/scenario')(scenStr)
Parses a scenario file.

* scenStr is a string containing the scenario

Returns An array of scenario data. Each scenario has the following properties:

* bucket A random number, ignore it
* map A path to the map data for the scenario.
* width the width of the map data in the map string
* height the height of the map data in the map string
* srcX the start X position
* srcY the start Y position
* dstX the goal X position
* dstY the goal Y position
* length` the optimal path length, assuming diagonal motion allowed
