Prototype the Edit Encounter form

[MikeTheCanuck]

Build a form that reads an Encounter's FullName property, displays it in an editable textbox, provides a Submit button, and pushes that data back to the same record as it came from.

Acceptance Criteria

1. Given there is at least one existing Encounter record
   When I select an existing Encounter record
   Then the Edit Encounter form opens AND
   Then the user is able to edit any of the Person, Event, Location, Topics fields.
2. Given the user has made a change to one of the fields in the Encounter data in the Edit form
   When the user taps the Save button
   Then the updated data will be written to the existing Encounter record, overwriting any previous values AND
   Then the Edit form disappears and the previous View is visible and interactive again.
3. Given the user has not made a change to any of the editable fields in the Edit form
   When the user taps the Save button
   Then the Edit form disappears and the previous View is visible and interactive again.
