+/**
+ * You're familiar with Billy Mitchell, World Video Game Champion? He could probably do it.
+ * So I gotta find a way to harness his power. And I think I've found a way.
+ * 
+ * THAT'S RIGHT, WE'RE GONNA CHEAT.
+ * 
+ * NBTStructures have the inherent flaws of the vanilla structure system: Structures are composed
+ * before terrain gen even kicks in, placement order of components are arbitrary and certain
+ * connected parts will fall apart due to unexpected variance in the terrain. Not good.
+ * The solution: Simply delay generation of parts using a tile entity that checks if the chunks
+ * in front of it are loaded, and then places a random part from the chosen pool. When this happens,
+ * the player is usually still far far away so they'll be none the wiser. Chunk load checks help
+ * prevent forced chunk loading and all the lag that comes with that.
+ * 
+ * The system is named after tandem shaped charges: Make a hole with the first charge, then deliver
+ * the actual payload.
+ *
