Reproduction steps:

1. Create new project
2. Create C# script
3. Include UnityEngine.Networking.Match library
4. Try create new instances of CreateMatchRequest, CreateMatchResponse, ListMatchResponse or JoinMatchResponse in Start method

Expected result: Instances can be created (No errors)
Actual result: Classes cannot be accessed due to its protecion level

This used to work before 5.4 release. Now the match making approach is changed and users cannot use the old approach.

Reproduced on: Unity 5.4.1f1, 5.4.2f1
Not reproduced on: Unity 5.25f1, 5.3.3f1

The documentation should also be updated to use new approach:

The example in this documentation currently does not compile
