Add example

[henrygerardmoore]

Currently, this example doesn't work and I'm not sure why. I was trying to make an example to show how to make an automatically managed shared ptr so that one could add logging to their application more easily. With this, the type is just std::shared_ptr<T> rather than std::shared_ptr<DataTamer::LoggedValue<T>> for a type T. Not sure this is necessary/useful, but I also figured it would be helpful for learning how to use DataTamer while making this example.

This builds and runs without error but doesn't log as I would expect. Maybe a better name than raii would be log_shared_ptr or something.

After some discussion, will be closing this as the functionality doesn't really add anything. The logging wouldn't be thread-safe in this case, so kind of defeats the purpose of having a shared pointer.
