See r6611 (http://svn.gna.org/viewcvs/relax?rev=6611&view=rev) for details.

Updated a copyright.

Fixes for the test_load_pdb() unit test.

Bug fix for the read_pdb() method.

The structural object is only created if it does not yet exist. This bug was causing the loss of
previously loaded files.

Added a check for the consistency of the PDB parser.

Removed a broken and useless test.

Converted the file_name structural object variable into a list.

This will allow multiple files to be opened within one data pipe.

Fixes for the internal PDB reader.

Non ATOM or HETATM records, after these records (i.e. CONECT) no longer cause the reader to fail.

Bug fix for the internal PDB reader, the HETATM records are now recognised.
