Example

var Tile = require('habitants-tile');
var tiles = {};

// These are your own creations
var mapTemplate = require('./mapdata/map.json');
var tileTemplates = require('./mapdata/tiletypes.json');

// Just loop over the 2D array and create tiles with locations, referenced by geokey! i.e '4:8', '32:89'
mapTemplate.forEach(function (row, yi) {
    row.forEach(function (tileType, xi) {
        var tileTemplate = tileTemplates[tileType];
        tileTemplate.location = {

        var tile = new Tile(tileTemplate);
        tiles[tile.toString()] = tile;
    });
});

// Check some out!
console.log(tiles['1:1'], tiles['2:4'], tiles['5:7']);
