Moved the old source code temporarily to src-old. This will be removed once the functionality has been transferred over into the new system.
The new design is based on algebraic principles. Thanks goes to sebcrozet and his nalgebra library for providing the inspiration for the algebraic traits: https://github.com/sebcrozet/nalgebra
Having these two modules separate made more sense when the library was divided into lmath and cgmath. Now that the two have been combined, it makes more sense to bundle these types in one module (I think).
