* 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.
