// # Application
// The Application module provides abstraction over the platform-specific Application implementations.
// It is the main BCL module and is required for other BCL modules to work properly.
// The default bootstrap.js implementation for each platform loads and initializes this module.
// ``` JavaScript
import app = require("application");
import platform = require("platform");
// ```
// The pre-required `app` module is used throughout the following code snippets.

// ### Checking the target platform
// Use the following code in case you need to check somewhere in your code the platform you are running against:
// ``` JavaScript
if (app.android) {
    console.log("We are running on Android device!");
} else if (app.ios) {
    console.log("We are running on iOS device");
