(Bridge.NET) ProductiveRage.Immutable.Collections

The ProductiveRage.Immutable/Bridge.Immutable library makes it easier to create with and work with imutable classes in Bridge.NET and introduced Optional<T> and NonNullList<T> types but there are other immutable collection types that are useful once you start writing writing immutable-by-default data structures.

Rather than implement any more myself, this library uses Facebook's Immutable JavaScript library but puts a more C#-style interface on top, where appropriate (and returns Optional<T> value from functions that may or may not return a value, such as the "GetIfPresent" function on the Map class).

This library will not necessarily expose all of the Facebook library's functionality or types, I will be adding data structures as I find them useful and trying to ensure that their interfaces are consistent

Map<TKey, TValue>

This is a dictionary-like struture that has the following interface:

uint Count { get; }
bool Contains(TKey key);
Optional<TValue> GetIfPresent(TKey key);
Map<TKey, TValue> AddOrUpdate(TKey key, TValue value);
Map<TKey, TValue> RemoveIfPresent(TKey key);

(as well as implementing IEnumerable<KeyValuePair<TKey, TValue>>).

This structure may be serialised/deserialised using Json.NET (using the .NET build of the library on the server if passing data from an API to a Bridge application or using the Bridge build of Json.NET).
