Load All Prefabs In Directory
/*
Helper script for loading all prefabs in a directory to a List
Not completely by me, found from: https://gist.github.com/HilariousCow/7f301b04c28fdf61e71f
With some modifications to return GameObjects instead of Components

//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".
