Merge pull request #712 in HDFFV/hdf5 from ~BMRIBLER/hdf5_1_8_bmr:hdf5_1_8 to hdf5_1_8

* commit '0b78905091a87002e788a22f94821ab16e045711':
  Update about C++ documentation
  Adding new C++ wrappers Description:     - Added overloaded wrappers for H5Oget_info and H5Oget_info_by_name         // Retrieves information about an object         void getObjectInfo(H5O_info_t *oinfo) const;         void getObjectInfo(const char *name, H5O_info_t *oinfo,                 const LinkAccPropList& lapl = LinkAccPropList::DEFAULT) const;         void getObjectInfo(const H5std_string& name, H5O_info_t *oinfo,                 const LinkAccPropList& lapl = LinkAccPropList::DEFAULT) const;     - Many miscellaneous cleanup for consistent appearance Platforms tested:     Linux/32 2.6 (jam)     Linux/64 (platypus)     Darwin (osx1010test)
