Class AnisotropyPlugin

Anisotropy Plugin Adds a material extension to PhysicalMaterial to support anisotropy maps. Anisotropy is a directional material property that causes the material to reflect light differently depending on the direction of the surface. This is useful for materials like brushed metal, fabric, etc. This is a separate implementation than the anisotropy property in three.js which satisfies KHR_materials_anisotropy glTF extension. It includes some additional properties like support for both rotation and directional maps(like Blender), noise, interfacing with the progressive plugin etc.

It also adds a UI to the material to edit the settings. It uses WEBGI_materials_anisotropy glTF extension to save the settings in glTF files.
