-    This class is the base class for {@link com.gtnewhorizon.structurelib.item.ItemConstructableTrigger} that defines

-    3 modes, <code>BUILDING</code>, <code>UPDATING</code>, and <code>REMOVING</code>. Each of these modes does as they
-    say, where building will build a new multi from scratch, updating will remove existing an existing structure and
-    replace it with new components (think upgrading glass on a multi, changing from a tier 1 to tier 2 of a multi, etc),
-    and removing will just straight up remove the multi.
