Changes:
- Added the ability to use sub schematics in a structure. The feature is similar to the Jigsaw block in vanilla Minecraft. (See here and here on how to use it)
- Added the ability to add a delay between the structure spawning and the replacement of signs and blocks.
- Loot tables can now be limited to specific container types. (For example: chests, trapped chest, hopper, brewing stand, and barrel.) ( See this page for more information).
