The `Unit` wrapper type ensures that elements of the underlying type has a unit norm.
For example, `Unit<Vector3>` designates an element of S².
In particular `UnitQuaternion<N>` is now a type alias for `Unit<Quaternion<N>>`.
Those are named DMat1 to DMat6 and have the same relation with DMat as DVec1 to DVec6 are related
to DVec.
As a side effect, the method `to_vec` of DMat was renamed `into_vec` to be more in line with the std lib.
Addresses the second point of #100.
Use `::angle_between` or `.angle_to` to compute the rotation angle between two vectors/rotation
matrices/unit quaternions.
Use `::rotation_between` or `.rotation_to` to compute the rotation matrix/unit quaternion to
transform a vector/rotation matrix/uniq quaternion to another.
Fix#130.
Use associated types for the `Outer` trait.
Add a `Repeat` trait for constructing a multidimensional value by repeating an element.
Split the `Diag` trait into `Diag` and `DiagMut`.
Implement `RustEncodable` for `Identity`.
The LMul, RMul and Scalar* traits were only necessary due to language
limitations regarding trait bounds that are now gone. The Mat trait is now
expressed in terms of regular operator traits.
However, due to the removal of these traits this constitutes a breaking change.
Resolves this error, which is fallout from

Fixes#52.
This renames pairs of methods like `normalize_cpy`, `normalize` to `normalize`
and `normalize_mut`. Note that the previous in-place operations had the same
name that now belongs to the copy operations. Therefore this is a breaking
change.
On a similar note, the `Quat::conjugate` method was also renamed to
`conjugate_mut` and a new copying method has taken its place. This appears to
be a similar issue (apart from the lack of the copy operation) and thus was
dealt with here, too.
Rot4 and Iso4 had to be left out, since Rot4 apparently lacks a working
constructor.
Thereby (almost) all types in nalgebra can now be used for quickcheck-style
testing.
"arbitrary" is now a conditionally compiled feature that contains these impls
adding a dependency on quickcheck.
