Updating documentation and TODO notes for 'ServerDataSource'
Creating non-anonymous versions of the JSONObjectRequest Request and Response handlers.
Creating a 'itemsToJSONAry' method that iterates over a list of Items, creates a JSONObject for each, and appends it to
a JSONArray to then be sent in a POST request. It seems providing a list of n Items to the JSONArray constructor results
in an array of n 'null' values.
