The .bootstrap(options) method was created for both the clientPage and requestPager. The clientPager should have this method called when it has been populated with all the Backbone collection data and need not call to the server. The requestPager should have this method called when the first page has been populated with all the Backbone collection and need not call to the server. Also, the .setDefaults() method was refactored out of the sync() method in the requestPager.
