         * The parameter `flat` (boolean, default true) gives each side its own normals. Set it to false to get a smooth continuous light reflection on the surface.
         * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE

         * * The parameter `subdivisions` sets the number of rings along the cylinder height (positive integer, default 1).
         * * The parameter `hasRings` (boolean, default false) makes the subdivisions independent from each other, so they become different faces.
         * * The parameter `enclose`  (boolean, default false) adds two extra faces per subdivision to a sliced cylinder to close it around its height axis.

         * * The value of n is the number of cylinder faces. If the cylinder has only 1 subdivisions, n equals : top face + cylinder surface + bottom face = 3
         * * Now, if the cylinder has 5 independent subdivisions (hasRings = true), n equals : top face + 5 stripe surfaces + bottom face = 2 + 5 = 7
         * * Finally, if the cylinder has 5 independent subdivisions and is enclose, n equals : top face + 5 x (stripe surface + 2 closing faces) + bottom face = 2 + 5 * 3 = 17
         * * Each array (color or UVs) is always ordered the same way : the first element is the bottom cap, the last element is the top cap. The other elements are each a ring surface.
         * * If `enclose` is false, a ring surface is one element.
         * * If `enclose` is true, a ring surface is 3 successive elements in the array : the tubular surface, then the two closing faces.

         * * The parameter `shape` is a required array of successive Vector3. This array depicts the shape to be rotated in its local space : the shape must be designed in the xOy plane and will be rotated around the Y axis. It's usually a 2D shape, so the Vector3 z coordinates are often set to zero
         * * The parameter `radius` (positive float, default 1) is the radius value of the lathe
         * * The parameter `tessellation` (positive integer, default 64) is the side number of the lathe
         * * The parameter `arc` (positive float, default 1) is the ratio of the lathe. 0.5 builds for instance half a lathe, so an opened shape
         * * The parameter `closed` (boolean, default true) opens/closes the lathe circumference. This should be set to false when used with the parameter "arc"
         * * The parameter `cap` sets the way the extruded shape is capped. Possible values : BABYLON.Mesh.NO_CAP (default), BABYLON.Mesh.CAP_START, BABYLON.Mesh.CAP_END, BABYLON.Mesh.CAP_ALL
         * * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
         * * If you create a double-sided mesh, you can choose what parts of the texture image to crop and stick respectively on the front and the back sides with the parameters `frontUVs` and `backUVs` (Vector4). Detail here : http://doc.babylonjs.com/babylon101/discover_basic_elements#side-orientation
         * * The optional parameter `invertUV` (boolean, default false) swaps in the geometry the U and V coordinates to apply a texture

         * Creates a polyhedron mesh
         * * The parameter `type` (positive integer, max 14, default 0) sets the polyhedron type to build among the 15 embbeded types. Please refer to the type sheet in the tutorial to choose the wanted type
         * * The parameter `size` (positive float, default 1) sets the polygon size
         * * You can overwrite the `size` on each dimension bu using the parameters `sizeX`, `sizeY` or `sizeZ` (positive floats, default to `size` value)
         * * You can build other polyhedron types than the 15 embbeded ones by setting the parameter `custom` (`polyhedronObject`, default null). If you set the parameter `custom`, this overwrittes the parameter `type`
         * * A `polyhedronObject` is a formatted javascript object. You'll find a full file with pre-set polyhedra here : https://github.com/BabylonJS/Extensions/tree/master/Polyhedron
         * * You can set the color and the UV of each side of the polyhedron with the parameters `faceColors` (Color4, default `(1, 1, 1, 1)`) and faceUV (Vector4, default `(0, 0, 1, 1)`)
         * * To understand how to set `faceUV` or `faceColors`, please read this by considering the right number of faces of your polyhedron, instead of only 6 for the box : http://doc.babylonjs.com/tutorials/CreateBox_Per_Face_Textures_And_Colors
         * * The parameter `flat` (boolean, default true). If set to false, it gives the polyhedron a single global face, so less vertices and shared normals. In this case, `faceColors` and `faceUV` are ignored
         * * You can also set the mesh side orientation with the values : BABYLON.Mesh.FRONTSIDE (default), BABYLON.Mesh.BACKSIDE or BABYLON.Mesh.DOUBLESIDE
         * * If you create a double-sided mesh, you can choose what parts of the texture image to crop and stick respectively on the front and the back sides with the parameters `frontUVs` and `backUVs` (Vector4). Detail here : http://doc.babylonjs.com/babylon101/discover_basic_elements#side-orientation
         * * The mesh can be set to updatable with the boolean parameter `updatable` (default false) if its internal geometry is supposed to change once created
         * @param name defines the name of the mesh
         * @param options defines the options used to create the mesh
         * @param scene defines the hosting scene
