The schema for Gistbook entities.
View gistook.md

author: The author
updatedAt: The datetime that the Gistbook was last updated as an ISO8601 string

toJSON is bad for serializing stuff.
View to-json-shim.js
 /* * toJSON Shim * Marionette 1.8.7 uses toJSON to serialize the model data for views, * which goes against the specifications of Backbone. toJSON should be * used for serializing your data back into JSON, primarily for the purposes * of returning it back to the server. Views should include their own version * of toJSON for display purposes. * * This is an open PR on Marionette and will be merged soon. *
