## Enhancements

API additions. New API functions in `Model` to customize the Phong material properties:

> specular color:

> > - `setNodesFaceSpecularColor`
> > - `unsetNodesFaceSpecularColor`
> > - `setNodesFaceSpecularIntensity`
> > - `unsetNodesFaceSpecularIntensity`

> ambient color:

> > - `setNodesAmbientColor`
> > - `setNodesAmbientMix`

> emissive color:

> > - `setNodesFaceEmissiveColor`
> > - `unsetNodesFaceEmissiveColor`

API additions. New API in `Model` to retrieve capping geometry from nodes (beta)

> - `getNodeCappingMeshData`
> - `getNodesCappingMeshData`

API additions. New API functions in `View` for a better lights management in the scene, now allows easy deletion and modification of lights and their properties

> - `getLightKeys`
