[svn-r15308] Purpose: Fixed bugs
Description: The class hierarchy was revised to address the problem reported in bugzilla #1068. Classes AbstractDS and Attribute are moved out of H5Object. Class Attribute now multiply inherits from IdComponent and AbstractDs and class DataSet from H5Object and AbstractDs. In addition, data member IdComponent::id was moved into subclasses: Attribute, DataSet, DataSpace, DataType, H5File, Group, and PropList. Platforms tested: SunOS 5.10 (linew) Linux 2.6 (kagiso) FreeBSD (duty)
