> STYLE PARAMETERS
> emissive : vec3 emissive color (unaffected by light), default [0.0, 0.0, 0.0]
> ambient : vec3 ambient color component, default [0.2, 0.2, 0.2]
> diffuse : vec3 diffuse color component, default [0.8, 0.8, 0.8]
> roughness : float surface roughness, 0 for smooth, 1 for matte, default 0.7
> albedo : float intensity of light reflection, 0 for dark, 1 for bright, default 0.7

npm install gl-lambert-material
Use with gl-material to generate a compiled shader, given a gl context and constants to replace
`javascript`
var lambert = require('gl-lambert-material')
var material = require('gl-material')(gl, lambert, {LIGHTCOUNT: 1})
Or just get the fragment shader for use elsewhere
`javascript``
var fragment = require('gl-lambert-material').fragment
