Improving tests

Description:
    - Added test for version bounds with nested datatypes
    - Added script for additional version bound test in h5repack
    - Cleaned up tests for consistency
    - Removed extra included header files
Platforms tested:
    Linux/64 (jelly)
    Linux/64 (moohan)
    Darwin (osx1010test)
