;; obs as [x1, x2, ..., xn] or [[x1, y1], [x2,y2], ..., [xn,yn]]
;; may also be lists, but pairs must be vectors
;; unsorted, numerical, positive values
;; otherwise garbage-in-garbage-out, probably exceptions

;; options are available to tweak sort order, sort by x or y, and legend of the curveUses Incanter for the curve graphs, Midje for the test suite.
