The Observer object no longer uses __init__() to setup structures as the singleton design kills it.

Fix for the new_analysis() method - it should be calling switch_page().

The Pipe_switch_observer singleton has also switched to the object base of Observer.

The Observer class is now using the new style python object construction.

Created the page_switch() method and registered it for pipe switches.

The new page_switch() method is registered with the Pipe_switch_observer singleton and observer
object so that pipe switches cause the notebook to switch pages. The switch_page() method has also
been created to abstract the switching of pages in the notebook.

Created generic_fns.pipes.Pipe_switch_observer for observing switches in the current data pipe.

Pipe_switch_observer.notify_observers() is now called by the switch() and delete() functions.

The User_functions class now derives from the Observer base class.

Added a module and base class method Observer which implements the observer design pattern.

Many bug fixes for the functions of the generic_fns.mol_res_spin module.

These fixes are for when a data pipe other than the current data pipe is used.
