-====== External Sources ======
-External data comes in from these sources:
-  - onScriptLoaded(subject data) - from pages/*.js
-    * flash.js switches the page and then passes data to Program object
-  - onLoadData(data) - from an external windows such as Sanskrit Keyboard
-    * postMessage: window.addEventListener("message", function(e) {
-    * flash.js reads the data to generate a new page and then passes data to Program object
-  - from getCards data service
-    * directly handled by Program object
-  - from localStorage
-    * onstartup
-    * when previous session is stored in localStorage
-Data Portal: \\
-program.loadData(data)\\
-Card(quest) constructor \\
-The incoming data object is external to the closure compiler,
-and therefore references to it must use brackets-quoted-string notation.
-  - We first pass the data object to program.loadData().
-  - Here the data is pulled out and loaded into internal objects, and the original external data object is discarded.
-  - The internal objects are then accessed by dot-notation.
