VertexLayout

Helper around creating vertex attributes in a given [[VertexBuffer]], this is useful for describing the memory layout for your vertices inside a particular buffer

Note: This helper assumes interleaved attributes in one [[VertexBuffer]], not many.

Working with gl.vertexAttribPointer can be tricky, and this attempts to double check you
