A simple shader variant collection tool for Unity 5.x

Unity's default behaviour is to postpone the compilation / optimization of a shader loaded at runtime until it appears on screen.

See ShaderVariantCollection.WarmUp document for more details.

It collects shader variants which will be used during a play session and save it out as an asset so which can be set on 'Graphics Setting', so it allows preloading that shaders which can prevent shader compilation problem causes cpu spike when a model is firstly shown.
