shall we disable realign_complexes()

[LilySnow]

Since we have a function to align PDB files, shall we disable realign_complexes() from hdf5?

realign_complexes() has the following issues:

1. It needs pssm files as input even though the not-aligned hdf5 file contains features_raw/PSSM_ALA_raw and so on.
2. It deletes the hdf5 file when an error occurs.

Sorry that we should have asked for this function in the first place.

yes it might be best ... i should have kept it as a quick fix and not part of the module.
