`BranchThreshold```

  Flag functions exceeding this number of control statements. The default is -1 (ignore the number of branches).

`ParameterThreshold```

  Flag functions that exceed a specified number of parameters. The default is -1 (ignore the number of parameters).

  Flag compound statements which create next nesting level after NestingThreshold. This may differ significantly from the expected value for macro-heavy code. The default is -1 (ignore the nesting level).
