/**
* @behavior lambert-material
* @class LambertMaterialBehavior -
* The `lambert-material` behavior gives any mesh a [Lambertian lighting model](https://en.wikipedia.org/wiki/Lambertian_reflectance)
* for its material. It uses a
* [THREE.MeshLambertMaterial](https://threejs.org/docs/index.html?q=lambert#api/en/materials/MeshLambertMaterial) under the hood.
*
* ## Example
*
* <live-code id="liveExample"></live-code>
* <script>
* liveExample.content = meshExample({material: 'lambert', color: 'skyblue'})
* </script>
*
* @extends MaterialBehavior
