/// These options are supported:
///
///   * `LineThreshold` - flag functions exceeding this number of lines. The
///     default is `-1` (ignore the number of lines).
///   * `StatementThreshold` - flag functions exceeding this number of
///     statements. This may differ significantly from the number of lines for
///     macro-heavy code. The default is `800`.
///   * `BranchThreshold` - flag functions exceeding this number of control
///     statements. The default is `-1` (ignore the number of branches).
///   * `ParameterThreshold` - flag functions having a high number of
///     parameters. The default is `-1` (ignore the number of parameters).
///   * `NestingThreshold` - 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).
///   * `VariableThreshold` - flag functions having a high number of variable
///     declarations. The default is `-1` (ignore the number of variables).
