    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);

  - groupBy
```
<V> UnsortedBagMultimap<V,T> groupBy(Function<? super T,? extends V> function)
```
    Description copied from interface: RichIterable
    For each element of the iterable, the function is evaluated and the results of these evaluations are collected into a new multimap, where the transformed value is the key and the original values are added to the same (or similar) species of collection as the source iterable.
