4c1cfb03cf ApproxEq trait enhanced with ULPs method of specifying closeness: 
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.

11a2b84ee0 Derive Copy wherever sensible 
Copy is now opt-in, see [1]. To keep the current library functionality it is
derived for all sensibly copyable types.

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.

Fixes #39.

77348f668f Use our own traits instead of the deprecated ones. 
We might switch to bjz/num-rs eventually (#32), but in the mean time we just re-declare the
deprecrated traits in nalgebra.

2b23446d54 Matrix Index/IndexMut implementation: return an element instead of a column. 
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.

de2479b70f Do not implement Transform<Vec*> for Vec*. 
This is error prone as this is a no-op for vectors and a translation for points.

70de340498 Remove the Iso * Vec overload and the ability to Transform a Vector with an Iso. 
This is too error prone as the user has to remember if he is using a vector or a point.
Istead, to transform a vector with an Isometry, use the internal rotation matrix of the isometry:
`iso.rotation * vector` instead of `iso * vector`.

The `Rotation` trait can also be used.

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).
