Do not export/use setools.InfoFlowAnalysis and setools.DomainTransitionAnalysis
    
    dta and infoflow modules require networkx which brings lot of dependencies.
    These dependencies are not necessary for setools module itself as it's
    used in policycoreutils.
    
    Therefore it's better to use setools.infoflow.InfoFlowAnalysis and
    setools.dta.DomainTransitionAnalysis and let the package containing
    sedta and seinfoflow to require python3-networkx
    
    Added new subpackage setools-console-analyses
