* General helper functions
This section contains general helper functions like ~trexio_info~.
~trexio_info~ prints information about the TREXIO configuration (see =config.h= file).
In particular:
1) ~TREXIO_PACKAGE_VERSION~ [string]
2) ~HAVE_HDF5~ [bool]
3) ~HDF5_VERSION~ [string] (optional, only if ~HAVE_HDF5~ is ~true~)
4) ~TREXIO_GIT_HASH~ [string]
