* This method creates a new Model based on the given triangulated vertices arrays.

* Adds vertices to this model by parsing the given arrays.
*
* This method will take vertex data in one of two formats, based on the `containsZ` parameter.
*
* If your vertex data are `x`, `y` pairs, then `containsZ` should be `false` (this is the default)
*
* If your vertex data is groups of `x`, `y` and `z` values, then the `containsZ` parameter must be true.
*
* The `uvs` parameter is a numeric array consisting of `u` and `v` pairs.
* The `normals` parameter is a numeric array consisting of `x`, `y` vertex normal values and, if `containsZ` is true, `z` values as well.
* The `indicies` parameter is an optional array that, if given, is an indexed list of vertices to be added.
*
* The following example will create a 256 x 256 sized quad using an index array:
*
* ```javascript
* const vertices = [
* -128, 128,
* 128, 128,
* -128, -128,

* const indices = [ 0, 2, 1, 2, 3, 1 ];
*
* Layer3D.addModelFromVertices(vertices, uvs, indicies);
