* Fix for bug #20471 (https://gna.org/bugs/?20471) - the is_empty() AttributeError when reading BMRB files. The problem was that the data pipe is_empty() method was not handling structural data correctly. The is_empty() method now belongs to the MolContainer objects rather than cdp.structure, and the object cdp.structure is not always present.
