+                1) OVERVIEW:
+
+Intercept chunk load and save events, at the NMS level.
+Decide which LAYER's version of the chunk to load from, and save to.
+  
+  Layers are like additional region folders, storing alternate
+  versions of the world.  
+
+
+
+
+
+                2) LAYERS:
+
+
+  SEED: 
+  the unmodified, from-seed version of each chunk
+  stored and NEVER CHANGED.
+  
+  
+  MODIFIED LAYER: 
+  multiple modified versions of the world
+  these can be associated with regions       
+      
+      
+    DEFAULT LAYERS:
+      
+      
+      WILDERNESS BUILD LAYER:
+      temporary changes made to the wilderness are stored here.
+      these chunks are periodically overwritten from SEED
+      
+      
+    OUR LAYERS:
+      
+      
+      "SERVER BUILD" LAYER
+      this layer contains Spawn, the dungeon-portal chunks, 
+      anything that is "part of the server"
+      
+      
+      TOWN LAYER:
+      this is the layer containing the stable, "official" peacetime contents of towns.
+      permanent changes, made by residents, are saved here.
+      
+      
+      OTHER:
+            
+            
+            SOFT CLAIMS LAYERS: 
+            every soft claim generates its own temporary layer
+            
+            
+            TEMPORARY MOVECRAFT PARKING:
+            want to park your craft without it being regenned to wilderness?
+            
+            
+            WILDERNESS EVENT REGIONS:
+            used for longer events taking place in the wilderness
+            maybe used for pitched battles?
+
+
+
+
+
+                3) LOGIC
+
+ 
+  REGION MANAGER:
+  region manager .yml declares which regions are working off which layers.
+  also declares any automated chunk regeneration (and which layer to regenerate from)
+  
+  
+  COMMAND MANAGER:
+  create commands for complex actions (such as toggling war) that have multiple steps.
+  possible steps: create or delete layers, or, modify settings in the region manager 
+  
+  
+  COMMAND SCHEDULER:
+  put a command on a clock
+
+
+
+
+
+                4) HOW WE WOULD USE THIS PLUGIN:
+
+
+  WAR:
+  During war, affected regions are placed in SANDBOX MODE. 
+  We create a temporary layer; war chunks are saved to, and loaded from, this temporary layer.
+  When war ends, the temporary layer is discarded. Return to using the TOWN LAYER.
+
+
+  WILDERNESS:
+  Changes made to the widerness are stored in the WILDERNESS BUILD LAYER.
+  When a chunk has not been modified for a while, it is reset from SEED.
