Unintuitive functions: to-map, to-dataset

[dmichulke]

(def ds (to-dataset (partition 3 (range 9)))) (= (to-map ds) (to-map ds)) ;; true (= ds (to-dataset (to-map ds))) ;; false, dataset becomes somehow transposed

PS: I do not mean that = does not work but that the data is really different, i.e., col-0 is (0 3 6) first and after mapping forth and back it is (8 7 6)
