 - flatCollect
```
public <V> ImmutableList<V> flatCollect(Function<? super T,? extends java.lang.Iterable<V>> function)
```
 Description copied from interface: RichIterable
 flatCollect is a special case of RichIterable.collect(Function). With collect, when the Function returns a collection, the result is a collection of collections. flatCollect outputs a single "flattened" collection instead. This method is commonly called flatMap.
 Consider the following example where we have a Person class, and each Person has a list of Address objects. Take the following Function:
 Function<Person, List<Address>> addressFunction = Person::getAddresses; RichIterable<Person> people = ...;
 Using collect returns a collection of collections of addresses.
 RichIterable<List<Address>> addresses = people.collect(addressFunction);
 Using flatCollect returns a single flattened list of addresses.
 RichIterable<Address> addresses = people.flatCollect(addressFunction);
