/**
* @brief This class implements a global object manager.
* @details This manager handles a list of available objects with system-wide
* relevance, such as device handlers, and TM/TC services. Objects can
* be inserted, removed and retrieved from the list. In addition, the
* class holds a so-called factory, that creates and inserts new
* objects if they are not already in the list. This feature automates
* most of the system initialization.
* As the system is static after initialization, no new objects are
* created or inserted into the list after startup.
