CBDL.startApp(function)
Function which is used to start the CBDL-based application that is passed
as its argument. The application, being an Object, requires, at bare minimum,
onInit(), onExecute(), and onLoop() member functions. This function then calls
onInit(), and if all goes well, to call onExecute().
What this effectively accomplishes is header/defines in the onInit, and a
base main() call in the onExecute().
Usage:
someApp = function() {
this.onInit = function() {
include("some_library.js");
};
this.onExecute = function() {
console.log("some_app executed!");
