"ignore" class function in README is incorrect

[bmgrimes]

The README documentation for the class "ignore" function is incorrect. It should read:

ignore: {
  class (name, value, defaultPredicate) {
    // disregard short classnames
    return name.length < 3 || defaultPredicate(name, value)
  }, ...

For me it was
ignore: { class(_, className) { return className.includes("class-to-ignore"); }, }
