Custom generator for property-based testing

[russel]

https://github.com/kotlintest/kotlintest/blob/master/doc/reference.md gives the example:

data class Person(val name: String, val age: Int)
class PersonGenerator : Gen<Person> {
    override fun always() = emptyList<Person>()
    override fun random() = generateSequence {
        Person(Gen.string().random().first(), Gen.int().random().first())
    }
}

but following this example with Kotlintest 3.1.0 reports that always is not a method in the interface Gen, and that constants is not defined. Is it just that the documentation is for 3.0.x and this is a breaking change for 3.1.x?

Yes I'll fix the docs and add a deprecated migration method.
