TileSet loading

Load a TileSet from the level map file to create corresponding Tile's and mapping.

TileSet = Tiles définition picked from an image

A SAmple TileSet class to understand what the challenge is:

class TileSet {
  Map <Code,Tile> tiles
  Image pixelsImage
}

In the level file test-level-tileset.lvl:

{
'name':'test-level-tileset',
'tileSets': [
  { 'id':'t01',
    'name':'myTileSet',
    'pixelsImage':'images/tiles/tiles01.png',
    'tiles':[
      {'code':'b','pos':(0,32),'size':(16,16),attributes:{'block':true}},
      {'code':'o','pos':(32,32),'size':(16,16),attributes:{'collectible':true,'money':5}},
      {'code':'n','pos':(64,0),'size':(16,16),attributes:{'collectible':true,'energy':20}}
    ]
 }]
}

The Use Case is:

Feature: Loading a Level

  The `LevelLoader` service is dedicated to load objects from a level file and initialize all corresponding entities.

  Scenario: 01- loading a TileSet
    Given the LevelLoader is instanciated
    And the level file "test-level-tileset.lvl" is loaded
    Then a level named 'test-level-tileset' is defined
    And a TileSet with 3 Tiles is created
    And the Tile with code 'b' has a 'block' attribute
    And the Tile with code 'o' has a 'collectible' attribute
    And the Tile with code 'n' has a 'collectible' attribute
