Stupid Unity scripts : "Smooth Follow" from Standard Assets

SmoothFollow.cs

// Smooth Follow from Standard Assets
// Converted to C# because I fucking hate UnityScript and it's inexistant C# interoperability
// If you have C# code and you want to edit SmoothFollow's vars ingame, use this instead.
