-Added proper third value indexing
-Thinking about generalizing that index class a bit
	  - Specifically, it should be possible to hold only some indexes
	  - This implies a hash of indices rather than slots
	    	 (which will simplify insertion and deletion some)
-Hopefully properly debugged higher-level index system
-Now watch as I proceed to use it only for single level indices -_-
-Removed test forms from index.lisp
-Removed all `format t` calls
-fact-bases now have default IDs
-load! updates its results' index
-load! takes a keyword argument to set starting indices
-added index! method to re-generate a given fact-bases' index
