but with trivial Pos and Scale)

bf31d81aac argh, gael you're more clever than i remembered. diagonal product is
optimized. so, i almost revert, just reordering to reduce # of
load/store.

251ecc0ab9 Rename someOrthogonal to unitOrthogonal. Fix a bug in it, with dyn-size vectors of size <=3.
Update doc and test to reflect that it always returns a unit vector.

ba100998bf * split Meta.h to Meta.h (generic meta programming) and XprHelper.h (relates to eigen mechanism)
* added a meta.cpp unit test
* EIGEN_TUNE_FOR_L2_CACHE_SIZE now represents L2 block size in Bytes (whence the ei_meta_sqrt...)
* added a CustomizeEigen.dox page
* added a TOC to QuickStartGuide.dox

* move the ioformat.cpp test to a documentation example
* rename IoFormat => IOFormat

f2f48b6560 * remove LargeBit and related stuff
* replaced the Flags template parameter of Matrix by StorageOrder
  and move it back to the 4th position such that we don't have to
  worry about the two Max* template parameters
* extended EIGEN_USING_MATRIX_TYPEDEFS with the ei_* math functions

2120fed849 * bug fixes in: Dot, generalized eigen problem, singular matrix detetection in Cholesky
* fix all numerical instabilies in the unit tests, now all tests can be run 2000 times
  with almost zero failures.

f0394edfa7 * bugfix in SolveTriangular found by Timothy Hunter (did not compiled for very small fixed size matrices)
* bugfix in Dot unroller
* added special random generator for the unit tests and reduced the tolerance threshold by an order of magnitude
  this fixes issues with sum.cpp but other tests still failed sometimes, this have to be carefully checked...

a814ebe180 fix a number of compiler errors and warnings with gcc 4.3. There was a missing
#include<algorithm> so I'm not sure how it compiled at all for you :)

db628c6ad7 Reimplement fitHyperplane such that the fit is done in a total LS sense
(use eigen decomposition).
Added optional feedback on the stability of the actual fit (think about fitting a 3D plane
on data lying on a line...)

0998c51d1f - remove the ASM macro as in fact Gael had been removing all the remaining
asm("...") from the code while fixing MSVC compat (so your changes crossed
  one another).
- move the pragma warning to CoreDeclarations, it's the right place to do early
  platform checks.

f729fc1d70 * Add the possibility to customize the output of matrices, e.g.:
IoFormat OctaveFmt(4, AlignCols, ", ", ";\n", "", "", "[", "]");
   cout << mat.format(OctaveFmt);
  The first "4" is the precision.
  Documentation missing.
* Some compilation fixes

591d497b84 add resize() methods to Map, doing nothing but assertions.
This is useful in Krita where I call lu().solve() with a Map object
as result. As solve() resizes the result, this was needed.

c705c38a23 * it's \returns not \Returns
* add some explanations in the typedefs page
* expand a bit the new QuickStartGuide. Some placeholders (not a pb since
it's not even yet linked to from other pages). The point I want to make is
that it's super important to have fully compilable short programs (even
with compile instructions for the first one) not just small snippets, at
least at the beginning. Let's start with examples of compilable programs.

104f8fd36e Added a SVD module:
- the decompostion code has been adfapted from JAMA
 - handles non square matrices of size MxN with M>=N
 - does not work for complex matrices
 - includes a solver where the parts corresponding to zero singular values are set to zero

a6d387a359 Various compilation fixes for MSVC 9. All tests compile but some
still fail at runtime in ei_aligned_free() (even without vectorization).

9466e5f94e * doc improvements in Cwise and PartialRedux:
- 33 new snippets
  - unfuck doxygen output in Cwise (issues with function macros)
  - more see-also links from outside, making Cwise more discoverable
* rename matrixNorm() to operatorNorm(). There are many matrix norms
  (the L2 is another one) but only one is called the operator norm.
  Risk of confusion with keyword operator is not too scary after all.

95dd09bea6 * revert the previous interface change in solveTriangular (pointer vs reference)
* remove the cast operators in the Geometry module: they are replaced by constructors
  and new operator= in Matrix
* extended the operations supported by Rotation2D
* rewrite in solveTriangular:
  - merge the Upper and Lower specializations
  - big optimization of the path for row-major triangular matrices

baf0cffedd *add operator()(int) for vectors, synonymous to operator[](int).
I don't see any reason not to allow it, it doesn't add much code, and
 it makes porting from eigen1 easier.
*expand tests/basicstuff to first test coefficient access methods

17ec407ccd * add Regression module, from eigen1, improved, with doc and unit-test.
* fix .normalized() so that Random().normalized() works; since the return
type became complicated to write down i just let it return an actual
vector, perhaps not optimal.
* add Sparse/CMakeLists.txt. I suppose that it was intentional that it
didn't have CMakeLists, but in <=2.0 releases I'll just manually remove
Sparse.
