Gaffer-specific Iterables and Iterators used when retrieving and manipulating data from stores.

Interface Summary
Interface Description

Validator<T>
An Validator validates objects of type T and returns true if they are valid.

Class Summary
Class	Description
AlwaysValid<T>	An `AlwaysValid` is an `Validator` in which it always returns true.
BatchedIterable<T>	A `BatchedIterable` is a `Closeable` `Iterable` of batches.
CachingIterable<T>	A `CachingIterable` is a `Closeable` `Iterable` that attempts to cache the iterable the first time it is read.
ConsumableBlockingQueue<T>	Extension to `ArrayBlockingQueue` to allow consumers to iterate over the queue, consuming the data, without being blocked.
EmptyIterable<T>	An `EmptyIterable` is a `Closeable` `Iterable` which is backed by a `EmptyIterator`, and contains no objects.
EmptyIterator<T>	An `EmptyCloseableIterator` is a `Closeable` `Iterator` which contains no objects.
LimitedInMemorySortedIterable<E>	An `Iterable` which can sort, limit and deduplicate its elements.
RepeatItemIterable<T>	A `RepeatItemIterable` is an `Iterable` which contains multiple copies of the same object.
RepeatItemIterator<T>	An `RepeatItemIterator` is an `Iterator` which contains multiple copies of the same object.
StreamFlatMapIterable<I,O>	A `StreamFlatMapIterable` is an `StreamIterable` which uses a `FlatMapStreamSupplier` to combine `Iterable`s.
StreamIterable<T>	A `Closeable` `Iterable` which uses a `Stream` as the underlying data source.
StreamIterator<T>	A `Closeable` `Iterator` to compliment the `StreamIterable`.
StreamMapIterable<I,O>	A `StreamMapIterable` is an `StreamIterable` which uses a `MapStreamSupplier` to combine `Iterable`s.
SuppliedIterable<T>	A `SuppliedIterable` allows a `Closeable` `Iterable` that can normally only be consumed once, be consumed multiple times.
TransformIterable<I,O>	A `TransformIterable` allows `Iterable`s to be lazily validated and transformed without loading the entire iterable into memory.
TransformOneToManyIterable<I,O>	A `TransformToMultiIterable` allows `Iterable`s to be lazily validated and transformed without loading the entire iterable into memory.
