Extend API

[FreezyLemon]

I'm currently trying to implement some const algebra and I've noticed some things that are available in other crates (like nalgebra) that would make sense in this crate:

• CMatrix::identity, CMatrix::zero
• A way to access the contained SoftF64 (make get public? maybe something like finish that returns [[SoftF64; C]; R] instead of [[f64; C]; R])
• A way to create a CMatrix/CVector from SoftF64s
• Dot product
• Cross product (not sure how easy this would be)

Thanks for filing an issue. Those all look pretty doable and useful. I'm happy to accept PRs implementing them, otherwise will start working on it as I have time

@FreezyLemon got all but cross product in, still thinking about that one. Are you mostly interested in it for a Vec3 equivalent or a general cross product?

[FreezyLemon]

Wow, that was quicker than I expected. I was specifically interested in doing cross products with CVector<3>, so I don't really need a general-case implementation.

But then again, writing a helper function for that specific case is relatively simple. It's not necessary if it makes the API worse :)

[knickish]

Ok great, glad it fixed your problem. just published v0.1.4 on crates with those changes. Will have a think on how to best implement general cross product

Thanks a lot!
