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

Mostly related to the `us` → `usize` suffix renaming. It turns out that none of
the suffixes are required any more, as the type inference appears to have
improved in that regard. There were also parantheses around range terms that
are not required any more.
Finally the `[]` syntax has been deprecated and thereby removed.
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.
approx_eq_ulps() allows specification of epsilon as an integer number
of Units in the Last Place (ULPs) difference between the two floating
point values
default approx_ulps() is set to 8.
approx_eq() function continues to use epsilon method, although I
recommend further commits and a migration towards the ULPs method.
