-------
+ - Fixed the slowness of regular hyperslab selection in a chunked dataset
+
+ It was reported that the selection of every 10th element from a 20G
+ chunked dataset was extremely slow and sometimes could hang the system.
+ The problem was due to the iteration and the building of the span tree
+ for all the selected elements in file space.
+
+ As the selected elements are going to a 1-d contiguous single block
+ memory space, the problem was fixed by building regular hyperslab selections
+ in memory space for the selected elements in file space.
