+       sparse_cases data structure that augments a sparse_array of cases
+       with the ability to dump cases to disk if we get too many cases in
+       memory.
+
+       * automake.mk: Add new files.
+
+       * sparse-cases.c: New file.
+
+       * sparse-cases.h: New file.

+
+       Adds a low-level on-disk case array data structure.
+       
+       * automake.mk: Add new files.
+
+       * case-tmpfile.c: New file.
+
+       * case-tmpfile.h: New file.

+
+       In a couple of places we calculate the maximum number of cases to
+       keep in memory based on the user-defined workspace.  Enable
+       centralizing the calculation through a new function.
+       
+       * settings.c (get_workspace_cases): New function.

+
+       The casenumber type is defined in transformations.h, but case.h is
+       a more sensible place.  Move it.
+
+       * case.h (CASENUMBER_MAX): New macro.
+       (typedef casenumber): Move here, from transformations.h.

        Slightly generalize case_to_values and case_from_values functions.
