+ * Innermost Loop: 32 attempts for deciding the maximum rooms in each dimension for the floor
+ * 		- The dimensions are capped at 6x4 (but we can randomize outside this range and fail)
+ * 		- Must maintain a certain number of tiles per grid cell in both dimensions
+ * 		- If this loop fails 32 times, defaults to a 4x4 maximum
+ *
+ * Inner Main Loop: 10 attempts for the main layout of a floor
+ * 		- This loop can fail by being marked invalid during generation
+ * 		- Or, it can fail by having < 2 rooms or < 20 room tiles
+ * 		- This occurs prior to secondary terrain generation
+ * 		- If the loop fails 10 times, defaults to generating a One-Room Monster House
+ *
+ * Outermost Loop: 10 attempts for everything involved in generating a layout
+ * 		- This is where secondary terrain generation and junction additions takes place
+ * 		- This loop can fail during spawn location verification (can you get to the stairs?)
+ * 		- If the loop fails 10 times, defaults to generating a One-Room Monster House
