/**
 * Controls the conversation page in the message drawer.
 *
 * This function handles all of the user actions that the user can take
 * when interacting with the conversation page.
 *
 * It maintains a view state which is a data representation of the view
 * and only operates on that data.
 *
 * The view state is immutable and should never be modified directly. Instead
 * all changes to the view state should be done using the StateManager which
 * will generate a new version of the view state with the requested changes.
 *
 * After any changes to the view state the module will call the render function
 * to ask the renderer to update the UI.
 *
 * General rules for this module:
 * 1.) Never modify viewState directly. All changes should be via the StateManager.
 * 2.) Call render() with the new state when you want to update the UI
 * 3.) Never modify the UI directly in this module. This module is only concerned
 *     with the data in the view state.
 *
 * The general flow for a user interaction will be something like:
 * User interaction: User clicks "confirm block" button to block the other user
 *      1.) This module is hears the click
 *      2.) This module sends a request to the server to block the user
 *      3.) The server responds with the new user profile
 *      4.) This module generates a new state using the StateManager with the updated
 *          user profile.
 *      5.) This module asks the Patcher to generate a patch from the current state and
 *          the newly generated state. This patch tells the renderer what has changed
 *          between the states.
 *      6.) This module gives the Renderer the generated patch. The renderer updates
 *          the UI with changes according to the patch.
