vchoi_fork

[svn-r2850] Purpose:
    Added new function.
Description:
    It's often convenient to query the class of a compound datatype's member
    to determine if it's an array and the previous way required you to open
    the member type to query it's class.
Solution:
    Added new H5Tget_member_class function to directly ask for the member type's
    class.
Platforms tested:
    FreeBSD 4.1.1 (hawkwind)
