6347b1db5b remove sentence "Eigen itself is part of the KDE project."
it never made very precise sense. but now does it still make any?

46fe7a3d9e if EIGEN_NICE_RANDOM is defined, the random functions will return numbers with
few bits left of the comma and for floating-point types will never return zero.
This replaces the custom functions in test/main.h, so one does not anymore need
to think about that when writing tests.

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...

c10f069b6b * Merge Extract and Part to the Part expression.
Renamed "MatrixBase::extract() const" to "MatrixBase::part() const"
* Renamed static functions identity, zero, ones, random with an upper case
  first letter: Identity, Zero, Ones and Random.

f5791eeb70 the big Array/Cwise rework as discussed on the mailing list. The new API
can be seen in Eigen/src/Core/Cwise.h.

54238961d6 * added a pseudo expression Array giving access to:
- matrix-scalar addition/subtraction operators, e.g.:
       m.array() += 0.5;
   - matrix/matrix comparison operators, e.g.:
      if (m1.array() < m2.array()) {}
* fix compilation issues with Transform and gcc < 4.1

486fdb26a1 many small fixes and documentation improvements,
this should be alpha5.

aebecae510 * find the proper way of nesting the expression in Flagged:
finally that's more subtle than just using ei_nested, because when
  flagging with NestByValueBit we want to store the expression by value
  already, regardless of whether it already had the NestByValueBit set.
* rename temporary() ----> nestByValue()
* move the old Product.h to disabled/, replace by what was ProductWIP.h
* tweak -O and -g flags for tests and examples
* reorder the tests -- basic things go first
* simplifications, e.g. in many methoeds return derived() and count on
  implicit casting to the actual return type.
* strip some not-really-useful stuff from the heaviest tests

522e24f2d7 update of the testing framework:
replaced the QTestLib framework my custom macros
and a (optional) custom script to run the tests from ctest.

b4a156671f * make use of the EvalBeforeNestingBit and EvalBeforeAssigningBit
in ei_xpr_copy and operator=, respectively.
 * added Matrix::lazyAssign() when EvalBeforeAssigningBit must be skipped
   (mainly internal use only)
 * all expressions are now stored by const reference
 * added Temporary xpr: .temporary() must be called on any temporary expression
   not directly returned by a function (mainly internal use only)
 * moved all functors in the Functors.h header
 * added some preliminaries stuff for the explicit vectorization

2ee68a074e generalized ei_traits<>.
Finally the importing macro is named EIGEN_BASIC_PUBLIC_INTERFACE
because it does not only import the ei_traits, it also makes the base class
a friend, etc.

6907886a15 prefix global functions with ei_ as previous solution was rather
fragile. also fix compilation with g++ 4.3.

84934ea217 - move: DerivedTraits becomes MatrixBase::Traits
- the static constants are private again in the Derived classes
- more documentation and code snippets
- new isDiagonal() method

dad245af56 - eigen2 now fully enforces constness! found a way to achieve that
with minimal code duplication. There now are only two (2)
  const_cast remaining in the whole source code.
- eigen2 now fully allows copying a row-vector into a column-vector.
  added a unit-test for that.
- split unit tests, improve docs, various improvements.
