Uploading images to Cloud Storage via the web and identifying them with Google Cloud Vision API

If you're trying to do this, you came to the right place!

/**
 * Send a bulk update to Firebase from an array or an object literal.

 * var childRef = ref.push();
 * 
 * A reference is returned which has a push-id that can be returned by calling .name().
