Notes on: src/lisp/table/nbins.lisp

How to load
	(load "games")
	(make-tables)
	(load "tables/nbin.lisp")
	(load "../../share/data/weathernumerics.lisp")
	(nth (weather-numerics) :n 3)
	: rsults should all be labelled 0,1,2

What does a table look like itnernally?
	run (make-data1) and see

How to get data out of a table
	2, 29, 30, 32,33,33

What are the valid accessors to a table?
	See src/lisp/table/structs.lisp

How to put data into a new table
	see general form of nbins

How turn a string to a symbol
	intern, 41

How turn a symbol to a string
	symbl-name, 43

How to case on type
	53,56,37,40

How to use inherited accessorts
	Note 44 header-name. Works for both column and numerics

How to define local functions inside a fnctions
	see "labels" in nbins

How to pass code as data
	34 becomes the "how" of discretize

How to do error handling (e.g. abort after n warnings)
	define on "caution" struct 
		: before processing that table
	carry it around 
		: over all the processsing
	example
		: nbins defines a "caution", 
		: sane numbers writes a caution

How to remove funny symbols from the numbers
	sane-numbers (line 4)
	 bug (exercise for the reader)
		: column of numbers will now be shorter after removal

How to runs columns into rows, with header data at the start of each row
	First, add the header list to the start of egs (51)
	Second, transpose columns to rows (50)
	Thirds, run down row (header data is at start of each row)
	Fourth, transpose back (47)

How to write another discretizer
	need a new top level driver (clone "nbins")
	need lowerest level worker (clone "nbins1")
	what you won't need
		 : a new discrete egs
