Important fix for the PipeContainer data structure.

All of the objects of the PipeContainer where being instantiated as objects of the class rather than
the separate instances. Hence two different PipeContainer instances contained the same objects!
All object instantiation is now done within the __init__() method to avoid the problem.

Modified generic_fns.residue.create() to replace the empty first residue if no residues exist.

Wrote two unit tests for testing the generic_fns.residue.create() function.

Fixes for the unit tests of the relax data storage singleton methods.

Alternative implimentation of the data object as a singleton.
