The notebook switches to the previous page if the current one is deleted now.

The notebook will now switch to a newly added analysis.

The number of analyses and current one are now being tracked.

Created the new Analysis_controller.analysis_data_loop() for returning the relax data store containers.

Created the new Analysis_controller.current_analysis_name() for returning the current analysis name.

Create the new Analysis_controller.get_page_from_name() method for returning an analysis page.

This is used by the results viewer to obtain the corresponding page.

Removal of a lot of old, unused code in the results viewer.

The relax data store is now imported.

Shifted code from relax_gui.state_load() to the new Analysis_controller.load_from_store().

This is to place all analysis code in the Analysis_controller class.
