6d841512c7 some hyperplane changes: 
- the coefficients are stored in a single vector
- added transformation methods
- removed Line* typedef since in 2D this is really an hyperplane
  and not really a line...
- HyperPlane => Hyperplane

9b4d46c82e * Add an HyperPlane class in the Geometry module 
with its respective unit-test.
  Feel free to discuss the API on the ML.
* Some bugfix in unitOrthogonal found by the hyperplane unit test.

3ced3f91c2 * temporarily remove doxygen customization, we'll see if that fix api.kde.org 
but I no hope, that would be too simple !
* added Rotation2D typedefs
* remove CoreDeclarations header file

f7de12de69 Missing inline keywords in AltiVec/PacketMath were making Avogadro fail 
to compile (duplicate symbols).

8f9d30cb20 * patch from Konstantinos Margaritis: bugfix in Altivec version of ei_pdiv 
and various cleaning in Altivec code. Altivec vectorization have been re-enabled
  in CoreDeclaration
* added copy constructors in non empty functors because I observed weird behavior with
  std::complex<>

5ac883b10a Fix a bug discovered in Avogadro: the AngleAxis*Matrix and the newer 
AngleAxis*Vector products were wrong because they returned the product
_expression_
   toRotationMatrix()*other;
and toRotationMatrix() died before that expression would be later
evaluated. Here it would not have been practical to NestByValue as this
is a whole matrix. So, let them simply evaluate and return the result by
value.

The geometry.cpp unit-test only checked for compatibility between
various rotations, it didn't check the correctness of the rotations
themselves. That's why this bug escaped us. So, this commit checks that
the rotations produced by AngleAxis have all the expected properties.
Since the compatibility with the other rotations is already checked,
this should validate them as well.

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

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

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...

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.
