    Parsing of a .include or .lib command. If the library exists and has not
    been called earlier, the path of the library will be stured in the list
    USERLIBS, and the library will be compiled (see: _compileUSERLibrary()).

    If the library does not exist the error count of the active circuit will be
    increased with one.

    The name of the active circuit object is the last name in the global
    CIRCUITNAMES: CIRCUITNAMES[-1]. The circuit object itself is stored in the
    dictionary CIRCUITS under this name: circuitDict[CIRCUITNAMES[-1]].

       1. In the absolute path or path relative to the project directory
       2. In the circuit directory (ini.circuitPath)
