First Submission of HKTMXTIledMap with Test
* Added Copyrights
* Made Blocks Optional
* elucidated ReadMe
Fixed HKTMXLayer to work with Retina Display
Integrated Jonathan Barnes's support for flipped tiles
* credit where credit is due
* updated known issues
Fixed broken animation code
* Fixed platformness of certain code
* Make sure we explicitly state we can use tileAt
* Added experimental features tileAt and setTile:At: which allow you similar functionalities to CCTMXTiledMap. These however will penalize performance advantages of using HKTMXTiledMap
* Added true support for scaling, so that you can set your max scale, and then work with it from there. Performance degrades the more tiles you draw, per usual, but it should still be better than CCTMXTiledMap
* more support for flipped tiles
* bug fix in tileAt such that the tile respects flippedness
Added support for CC_FIX_ARTIFACTS_BY_STRECHING_TEXEL
* added support for one shot animations via setTileGID
* Fixed bug involving oneshot animations involving more than 2 frames
