Some organisational prep work before I start working on a new navigation method (ie replacement for CardSelector). The current design was to allocate a CardSelector and pass in its pointer to a variety of classes via their constructors. To simplify things, now we use a singleton style pattern with an Instance() function - this means that when I implement a new class to replace CardSelector, I only need to modify what's returned by the singleton callback - as long as the new pointer class supports the same function calls, it'll be a straight drop-in.
