Implement persistence in AtEvent switch state
Add event_profile activity
This activity allows the user to determine which data to display in the attendees list for a particular event.
The activity will consist of a series of elements.  Each element will have a tile (i.e. name, address,
company, school, hobbies, etc), current value of each field, and a switch to display or hide the information.
In addition, there will be an edit text box that allows the user to enter specific information for this event.
