Hello all,

I have some question about finding the normal vector of the faces in the mesh using GeometryTypes.jl  
In GeometryTypes.jl, I can calculate the normal of the vertices using normals(mesh), is there any function to find the normal of the triangle faces? I can not find it in GeometryTypes documentation.
