A Firebase App holds the initialization information for a collection of services.

Do not call this constructor directly. Instead, use firebase.initializeApp() to create an app.

The default app's name is "[DEFAULT]".

// A named app's name is what you provide to initializeApp()
var otherApp = firebase.initializeApp(otherAppConfig, "other");
console.log(otherApp.name);  // "other"

options
