+ * Implements a simple timer which calls a method after a specified timeout in ms.
+ * This timer can be canceled using "cancelTimer()"
+ *
+ * This source file is a part of the NodeStateAccess library (NSMA).
+ * The architecture requires that the NodeStateManager (NSM) is independent from the D-Bus binding and code generated by
+ * "CommonAPI". Therefore, the D-Bus communication and generated CommonAPI objects are handled inside of this library.
+ * The library offers the NSM an interface to use objects generated via CommonAPI.
