Contributions summary:Nikhil implemented several methods to verify the equality of different types of multimaps, including list, set, bag, sorted set, and sorted bag multimaps. These methods provide functionality for testing collections with complex data structures. Furthermore, the user added a method to support converting an iterable to a multimap and also added support for the select, reject, and collect iteration patterns. Several commits include adding unit tests to verify the functionality of the new methods.

Contributions summary:Nikhil contributed to the GS Collections library, focusing on enhancing its functionality. Their work involved adding new constructors to classes such as `UnifiedMap` and `UnifiedSetMultimap` to support the construction of maps and multimaps using `Iterable<Pair<K, V>>`. The user also implemented methods like `swap()` for `Pair` and `collectValues()` for maps, along with implementing methods for selecting and rejecting keys and values in the Multimap interface. These changes improved the usability and flexibility of the library's core data structures.
