Build Requirements:	Xcode 8.0, iOS 9.0 SDK, OS X 10.11 SDK
Runtime Requirements:	iOS 9.0, OS X 10.11

The Network Extension framework exposes APIs that give you the ability to customize the networking features of iOS and OS X. This sample project demonstrates how to:

- Use the NEPacketTunnelProvider class to implement a custom VPN tunneling protocol. - Use the NETunnelProviderManager class to create and manage VPN configurations that use the custom VPN tunneling protocol. - Use the NEAppProxyProvider class to implement a custom transparent network proxy protocol. - Use the NEAppProxyProviderManager class to manage VPN configurations that use the transparent network proxy protocol. - Use the NEFilterControlProvider and NEFilterDataProvider classes to implement a custom on-device content filtering service. - Use the NEFilterManager class to configure the custom filtering service.
