Extending the Unity Editor for the Observable Pattern

Recently I have been on a quest to discover and understand as many programming design patterns as I can. This happened after I had a huge light bulb moment where I realized that programming design patterns could actually dramatically shift my thinking, especially with regards to game design.

One of those patterns that I really like is the Observable pattern or a reactive pattern. It felt like a massive paradigm shift to be able add this to my conceptual programming framework. It allows for a much simpler and cleaner integration for events, such as leveling up or achievements.

Unfortunately while trying it out in Unity3D I realized that C# properties, which is a pretty straightforward way to implement this pattern, does not play nicely with the Unity3D Inspector Editor. Hence I developed a neat little property attribute to address the issue.
