 * Companion Objects
An object declaration inside a class can be marked with the companion keyword:
class MyClass {
companion object Factory {
fun create(): MyClass = MyClass()
}
}
Members of the companion object can be called by using simply the class name as the qualifier:
 */
companion object {
    private val TAG = CameraIntentActivity::class.java.simpleName
    private val MY_PERMISSIONS_REQUEST_OPEN_CAMERA = 10
    private val REQ_RESULT_CODE_CAMERA = 2
}
