There is no reason why indexing would prefer returning a column instead of a line. Instead, we
return an element, and let the user use the `Col` and `Row` traits istead.
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.
Everything changed, hopefully for the best.
* everything is accessible from the `na` module. It re-export
everything and provides free functions (i-e: na::dot(a, b) instead of
a.dot(b)) for most functionalities.
* matrix/vector adaptors (Rotmat, Transform) are replaced by plain
types: Rot{2, 3, 4} for rotation matrices and Iso{2, 3, 4} for
isometries (rotation + translation). This old adaptors system was to
hard to understand and to document.
* each file related to data structures moved to the `structs` folder.
This makes the doc a lot more readable and make people prefer the
`na` module instead of individual small modules.
* Because `na` exists now, the modules `structs::vec` and
`structs::mat` dont re-export anything now.
As a side effect, this makes the documentation more readable.
