+ * Used to override which blocks may be stored in a given chunk.

+ * that don't fit into the {@link IDhApiBlockStateWrapper} format DH requires
+ * (IE modded blocks that use NBT data
+ * to determine their model and/or texture). <br/><br/>
+ *
+ * This event is fired for each block or biome change when DH is processing a chunk.
+ * A change happens when DH finds a different block or biome while walking through a chunk.
+ * For example with the block sequence:<br/>
+ * <code> stone -> stone -> air -> stone </code> <br/>
+ * This event would be fired for the first, third, and forth blocks in the sequence
+ * (IE the first stone, first air, and last stone respectively). <br/> <br/>
+ * 
+ * The order DH will process blocks is undefined so a specific ordering shouldn't be relied upon for your logic to function. <br/> <br/>
+ * 
+ * <b>Threading note:</b> this event may be called concurrently across multiple threads. <br/>
+ * <b>Performance note:</b> this event will be called very frequently, avoid expensive lookups or other slow operations if possible. <br/>
