[svn-r5428]
Purpose: New Feature - per library change Description: Added the new member function getMemberIndex to classes EnumType and CompType to match the new C API H5Tget_member_index. Given the name of a member of an enumeration or compound datatype, this new function queries the index of the member. Platforms: SunOS 5.7 (arabica) Linux 6.2 (eirene)
