/*
The resource manager can lookup assets by name and classID.
An resource file is generated with the editor. And is shipped with unity.
It provides the most basic assets necessary to run unity.
Eg. some shaders, some textures for lighting
If you want to add a new resource to the ResourceManager:
- Call RegisterResource inside InitializeResources (Use a unique id and never reuse an id)
- Open a project with the resources you want to add
All resources have to be placed inside a "Assets/DefaultResources"
- When you have assembled all the resources. Use BuildResources from the main menu.
This will Install them in the right folder and also
invoke installframeworks so it is installed in all versions of the editor
