Load All Prefabs In Directory

    //So, there's no "load all assets in directory" function in unity. 
    //I guess this is to avoid people using Prefabs as "data blobs". 
    //They'd rather you use ScriptableObjects... which is fine in some cases, 
    //but sometimes the thing you're blobbing is just a bunch of child transforms anyway,
    //so it's huge buckets of sweat to reproduce the scene tools unity already has. 
    
    //The "AssetsDatabase.LoadAllAssetsAtPath" refers to /compound/ raw assets,
    //like maya files. But it doesn't care about humble prefabs, 
    //which are more like compounds of assets, rather than raw assets.
    
    //This function collates all the the behaviours you want in the directory you point it at. The path is relative to your Assets.
    //i.e. "Assets/MyDirectory/"
    //It returns the Prefab References, remember! Not instantiated scene objects! 
    //So it's only used for *editor-side* tools. Not run time.
    //Quite useful in conjunction with "PrefabUtility".
