Dhii - Iterator - Helper - Base

Common functionality for working with iterables.

Traits

• ResolveIteratorCapableTrait - Retrieves the deepest iterator within a depth limit in an iterator hierarchy, where every parent is an IteratorAggregate. Can use a complex test to look for things that are not only iterators. Detects some signs of infinite recursion.
• CountIterableCapableTrait - Counts elements in an iterable which passes normalization by NormalizeIterableCapableTrait. Uses the most optimal method for retrieving the count.
• NormalizeIteratorCapableTrait - Normalizes any iterable that passes normalization by NormalizeIterableCapableTrait into an instance of Iterator.
• MapIterableCapableTrait - Maps an iterable, similarly to array_map() or iterator_apply().
