[svn-r1132] Dataset region references are now finished and working correctly. Also, there

are five new API functions for querying selections:
    H5Sget_select_hyper_nblocks     - retrieves the number of hyperslab blocks
                                        in current hyperslab selection for a
                                        dataspace
    H5Sget_select_elem_npoints      - retrieves the number of element points
                                        in current element selection for a
                                        dataspace
    H5Sget_select_hyper_blocklist   - retrieves a list of the hyperslab blocks
                                        in current hyperslab selection for a
                                        dataspace
    H5Sget_select_elem_pointlist    - retrieves a list of the element points
                                        in current element selection for a
                                        dataspace
    H5Sget_select_bounds            - retrieves a n-dimensional bounding box
                                        containing current selection.

+ NAME
+    H5S_all_bounds
+ PURPOSE
+    Gets the bounding box containing the selection.
+ USAGE
+    herr_t H5S_all_bounds(space, hsize_t *start, hsize_t *end)
+        H5S_t *space;           IN: Dataspace pointer of selection to query
+        hsize_t *start;         OUT: Starting coordinate of bounding box
+        hsize_t *end;           OUT: Opposite coordinate of bounding box
+ RETURNS
+    Non-negative on success, negative on failure
+ DESCRIPTION
+    Retrieves the bounding box containing the current selection and places
+    it into the user's buffers.  The start and end buffers must be large
+    enough to hold the dataspace rank number of coordinates.  The bounding box
+    exactly contains the selection, ie. if a 2-D element selection is currently
+    defined with the following points: (4,5), (6,8) (10,7), the bounding box
+    with be (4, 5), (10, 8).  Calling this function on a "none" selection
+    returns fail.
