Updates:
 - Trying to create a better data model so I can add more features to the list view
Created an OAAccounting object.  Did some simple test data and JSON object parsing.
OANode is loads a global structure and the ListView is built from it.
Minor changes.
Saving and retrieving the OANode system information from the SharedPreference data structure.
Able to sort the JSON objects using the 'enable' field.  Going to add the ability to sort by the different fields.
Created a context that popups a menu to filter the OANode results.
Implemented a list filter based on the system being ENABLED/DISABLED
