50417494ec Use same algorithm to solve 2x2 eigenvalue problem
The eigenvalue problem is solved in two different method that use different methods
to calculate the discriminant of the solution to the quadratic equation.
Use the method whose computation is considered more stable.

667c49d0e1 Correct Schur decomposition for 2x2 matrices
Due to rounding and possible loss of precision the lower left element of the 2x2 matrix
may be different from zero.

d45c242a15 Add a Unit wrapper type, remove UnitQuaternion.
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>>`.

bd593a923c Fix a number of warnings
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.

3107dd607b Rename similar in-place and copy methods
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.
