These changes implement STUD-813. The commit consists of the following logical changes: - a REST API has been implemented for a course's assets - the page itself now fetches the assets client-side - the Backbone.Paginator library is used to support pagination - the AssetCollection has been refactored to extend Backbone.Paginator.requestPager so that it can be paged - an abstract PagingView class has been added to generalize the communication with a paging REST API - the AssetsView has been reimplemented to extend PagingView - two new child views have been added: - PagingHeader: the paging controls above the list of assets - PagingFooter: the paging controls below the assets

/* These utility methods are used by Jasmine tests to create a mock server or
|
|
* get reference to mock requests. In either case, the cleanup (restore) is done with
|
|
* an after function.
|
|
*
|
|
* This pattern is being used instead of the more common beforeEach/afterEach pattern
|
|
* because we were seeing sporadic failures in the afterEach restore call. The cause of the
|
|
* errors were that one test suite was incorrectly being linked as the parent of an unrelated
|
|
* test suite (causing both suites' afterEach methods to be called). No solution for the root
|
|
* cause has been found, but initializing sinon and cleaning it up on a method-by-method
|
|
* basis seems to work. For more details, see STUD-1040.
