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>>`.

581251d5b4 Implement dynamic matrix with a maximum size. 
Those are named DMat1 to DMat6 and have the same relation with DMat as DVec1 to DVec6 are related

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.

ea86890647 Add the RotationTo trait to compute the delta rotation between two elements. 
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.

730dc40b01 Remove operator hacks 
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.

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.

1103996b83 Implement Arbitrary for (almost) all types 
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.

edaeab72ac Use object-oriented style for trait methods 
Wherever sensible the geometric traits now take `&self` arguments, so that
implementations can be invoked as instance methods instead of static methods.
This makes some idioms easier to express and generally allows for greater
flexibility as the restructured methods can still be invoked like static
methods.

924d8269d8 Add points. 
This adds the Pnt{1,2,3,4,5,6} structures.
This adds the traits:
  − AnyPnt
  − FloatPnt
  − PntExt
  − FloatPntExt
  − Orig (to return the zero point)
  − PntAsVec
  − VecAsPnt
This adds operator overloading:
  − Pnt + Vec
  − Pnt - Vec
  − Pnt * Scalar
  − Pnt / Scalar
  − Pnt + Scalar
  − Pnt - Scalar
  − Iso * Pnt
  − Rot * Pnt
  − Pnt * Iso
  − Pnt * Rot
This changes some behavior:
  − Iso multiplication with a Vec does not translate the vector any more.
  − ToHomogeneous adds a 0.0 at the end of a Vec and a 1.0 at the end of a Pnt.
  − FromHomogeneous performs w-normalization on a Pnt, but not on a Vec.
  − The Translate<Vec> trait is never implemented (i-e. a Vec is not to be translated).

Note that `na::PartialOrd` is not the same as `cmp::PartialOrd`
(which lacks a lot of partial ordering operators).
