collections-by - extensions for Sequence and Iterable

Provides overloaded functions - for Iterable, Sequenece, List and Array - taking a predicate. Overloaded functions take an additional selector parameter, in addition to predicate or object to match. E.g.findBy, removeAllBy.

Two overloads are generated for each function and underlying collection:

• with selector and object-to-equal
• with selector and predicate

// same set of overloads are also generated for Sequence, Array etc
fun <T, U> List<T>.findBy(selector: (T) -> U, predicate: (U) -> Boolean): List<T>
fun <T, U> List<T>.findBy(selector: (T) -> U, match: U): List<T>

// usage
people.findBy(Person::surname, "Papari")
people.findBy(Person::surname) { name -> name == "Papari" }
