Should the README use the bundled Nalgebra version?

[TheCynosure]

The example on the README uses nalgebra as an external crate but when I ran this locally it complained of Kiss3d functions (particularly from_axis_angle) unable take Nalgebra objects but needed kiss3d::nalgrebra objects instead.

I think these lines in the README needs to be changed from:

extern create nalgebra as na;

use na::{Vector3, UnitQuaternion};

To

use kiss3d::nalgebra::{Vector3, UnitQuaternion};

Also just let me know if there is a way around this to use an external version of nalgebra that differs from the bundled version.

EDIT: I see this is acknowledged further down in the README, but if you are forced to used the same version of Nalgebra as Kiss3d anyways it might be easier for users to just use the bundled version.

I'd approve a PR for this, if you want to make one. It's true that nalgebra compatibility issues are a pain point, particularly for users who want to use a different version.
