Python: Is File Open?

[ax3l]

@yyalli currently it is not possible to query if a f=adios.File object is still open (e.g., after a call to .close()).

One way would be to implement a cast of adios.File to bool (as h5py does it) which leads True if the internal f.fp is != NULL and False otherwise.

Alternatively, an f.is_open() call could be implemented with the same behaviour.

This is necessary to finish our HDFCompass pull request (https://github.com/HDFGroup/hdf-compass/issues/155).

Just implemented is_open() as well as boolean cast functions (nonzero and bool) for adios file.
