Compression by TheTemportalist

Allows player to compress all normal blocks (cobble, grass, stone, etc.) and any non-data item (apples, sticks, diamonds, etc.) into large stacks. You can use these stacks much like normal blocks. Once each stack gets large enough, certain affects kick in. Some can become blackholes sucking in all items they are like, much like a magnet for a specific item. Great for large storage.
