Checks for large functions based on various metrics.

## Options

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 that exceed a specified 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 exceeding this number of variables declared in the body. The default is -1 (ignore the number of variables). Please note that function parameters and variables declared in lambdas, GNU Statement Expressions, and nested class inline functions are not counted.
