vchoi_fork

[svn-r2707] Purpose:
    Optimization for parallel I/O
Description:
    When contiugous hyperslabs are defined (i.e. with the block=stride), the
    library was only aggregating the hyperslabs together for the fastest
    changing dimension.
Solution:
    Add some extra code to detect when contiguous hyperslabs span more than one
    row and output the entire contiguous section at once.
Platforms tested:
    FreeBSD 4.1.1 (hawkwind)
