Synopsis [Initialization procedure for the library project.]

Description [Note that when Abc_Start() is run in a static library project, it does not load the resource file by default. As a result, ABC is not set up the same way, as when it is run on a command line. For example, some error messages while parsing files will not be produced, and intermediate networks will not be checked for consistancy. One possibility is to load the resource file after Abc_Start() as follows: Abc_UtilsSource( Abc_FrameGetGlobalFrame() );]
