Merge pull request #122 in HDFFV/hdf5 from ~DEROBINS/hdf5_der:eoc_groups to develop

Merged EoC for groups. Will expand the tests as discussed in the code review at a later date.

* commit '30f5f7d9f97e7e4e331894c3574cc1b6c4df6d9e':
  Removed commented-out lines that clean up test files.
  Added a test for old- and new-style groups under evict-on-close.
  Evict-on-close now works with groups.
