Implement ConfigHelper class
Contains mostly static methods useful elsewhere
- getProviders() could return a list of preseeded providers if we will use this outside of wizard (not likely)
- Since we're parsing Strings of JSON from file, HTTP Response, and SharedPreferences values into JSONObjects in our different classes, having a static rescueJSON(JSONException e, etc) method to call in the catch of try/catch should go here.
- What else makes sense here?
