This lightweight extension allows data to be saved between runtimes. While the system functions much like UnityEngine.UserPreferences, this extension allows the developer to save any serializable class and all structures. The file that is exported in written and read using standard .NET XML functions, but can be saved with a custom extension to prevent tampering. Implementation is quick and easy- just be sure all saved classes are marked with the 'serializable' attribute, and that all serialized fields are public. Files can be saved and loaded to any path, but are saved in the streaming assets path by default.
