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).

Version of rustc: 0.11.0-pre-nightly (faa7ba7 2014-05-31 01:06:40 -0700).
Main changes:
* `cmp::Ord` -> `cmp::PartialOrd`
* `cmp::Eq` -> `cmp::PartialEq`
Note that `na::PartialOrd` is not the same as `cmp::PartialOrd`
(which lacks a lot of partial ordering operators).
The ColSlice implementation for fixed size matrices returns a DVec,
while this is probably not optimal performance-wise, the dynamic nature
of the result makes this necessary. Using a data type presenting the
ImmutableVector trait would solve this, but it looks like a non-trivial
change.
This allows the implementation of householder reflection without relying
on knowledge of DVec. This required a new member in the Indexable trait:
the shape() function, which returns the maximum index available.
this is a first sketch, the algorithm is not yet initialized and relies
on knowledge of DMat internals. A next step would be to implement this
algorithm in a more generic manner.
Those are `Vec3MulRhs`-like traits that allow the simulation of haskellish fundeps to allow multiple
overloads of builtin operators (* / + -).
They are all on the `na::overload` module.
The `Vec` trait is renamed `AnyVec`.
The `Less`, `Greater`, `Equal` variants are renamed `PartialLess`, `PartialGreater`,
`PartialEqual`.
Those new names are not very good, so they might change in the future.
Version of rustc: 0.10-pre (b0ce960 2014-02-17 22:16:51 -0800)
This replaces uses of the `Orderable` trait by a `PartialOrd` trait: the `min` and `max` methods
are replaced by `inf` and `sup` methods.
Vectors do not implement the `Ord` trait any more.
