25f8adfa6c * Fix bug #79: ei_alignmentOffset was assuming that ptr is multiple of
sizeof(Scalar), and that assumption breaks with double on linux x86-32.
* Rename ei_alignmentOffset to ei_first_aligned
* Rewrite its documentation and part of its body
* The variant taking a MatrixBase doesn't need a separate size argument.

5cb779e5e1 * introduce ei_alignmentOffset(MatrixBase&,Integer)
couldnt put it in Memory.h as it needs the definition of MatrixBase
* make Redux use it

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

113fc3a260 now if Derived has the DirectAccess flag, then MatrixBase<Derived>::coeff() const returns a const Scalar& and not a Scalar as before.
useful for people doing direct access. + 1 bugfix thanks to Patrick Mihelich, forgot a & in MapBase::coeff(int).

5f6fbaa0e7 * fix a vectorization issue in Product
* use _mm_malloc/_mm_free on other platforms than linux of MSVC (eg., cygwin, OSX)
* replace a lot of inline keywords by EIGEN_STRONG_INLINE to compensate for
  poor MSVC inlining

cb409914e0 * call it beta2
* improvements in Matrix documentation
* document copyCoeff and copyPacket even if it's hidden from doxygen

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

4fa40367e9 * Big change in Block and Map:
- added a MapBase base xpr on top of which Map and the specialization
    of Block are implemented
  - MapBase forces both aligned loads (and aligned stores, see below) in expressions
    such as "x.block(...) += other_expr"
* Significant vectorization improvement:
 - added a AlignedBit flag meaning the first coeff/packet is aligned,
   this allows to not generate extra code to deal with the first unaligned part
 - removed all unaligned stores when no unrolling
 - removed unaligned loads in Sum when the input as the DirectAccessBit flag
* Some code simplification in CacheFriendly product
* Some minor documentation improvements

c94be35bc8 introduce copyCoeff and copyPacket methods in MatrixBase, used by
Assign, in preparation for new Swap impl reusing Assign code.
remove last remnant of old Inverse class in Transform.

e27b2b95cf * rework Map, allow vectorization
* rework PacketMath and DummyPacketMath, make these actual template
specializations instead of just overriding by non-template inline
functions
* introduce ei_ploadt and ei_pstoret, make use of them in Map and Matrix
* remove Matrix::map() methods, use Map constructors instead.

c5bd1703cb change derived classes methods from "private:_method()"
to "public:method()" i.e. reimplementing the generic method()
from MatrixBase.
improves compilation speed by 7%, reduces almost by half the call depth
of trivial functions, making gcc errors and application backtraces
nicer...

25ba9f377c * add bench/benchVecAdd.cpp by Gael, fix crash (ei_pload on non-aligned)
* introduce packet(int), make use of it in linear vectorized paths
  --> completely fixes the slowdown noticed in benchVecAdd.
* generalize coeff(int) to linear-access xprs
* clarify the access flag bits
* rework api dox in Coeffs.h and util/Constants.h
* improve certain expressions's flags, allowing more vectorization
* fix bug in Block: start(int) and end(int) returned dyn*dyn size
* fix bug in Block: just because the Eval type has packet access
  doesn't imply the block xpr should have it too.

bb1f4e44f1 * Block: row and column expressions in the inner direction
now have the Like1D flag.

* Big renaming:
  packetCoeff ---> packet
  VectorizableBit ---> PacketAccessBit
  Like1DArrayBit ---> LinearAccessBit

4317fad869 * Added several cast to int of the enums (needed for some compilers)
* Fix a mistake in CwiseNullary.
* Added a CoreDeclarions header that declares only the forward declarations
  and related basic stuffs.

678f18fce4 put inline keywords everywhere appropriate. So we don't need anymore to pass
-finline-limit=1000 to gcc to get good performance. By the way some cleanup.

f279162ec4 * introducte recursive Flags system for the expressions
-- currently 3 flags: RowMajor, Lazy and Large
 -- only RowMajor actually used for now

729618c945 * #define EIGEN_NDEBUG now also disables asserts. Useful
to disable eigen's asserts without disabling one's own program's
  asserts. Notice that Eigen code should now use ei_assert()
  instead of assert().
* Remove findBiggestCoeff() as it's now almost redundant.
* Improve echelon.cpp: inner for loop replaced by xprs.
* remove useless "(*this)." here and there. I think they were
  first introduced by automatic search&replace.
* fix compilation in Visitor.h (issue triggered by echelon.cpp)
* improve comment on swap().

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.

01572b9f54 big change: MatrixBase only takes one template parameter "Derived", the
template parameter "Scalar" is removed. This is achieved by introducting a
template <typename Derived> struct Scalar to achieve a forward-declaration of
the Scalar typedefs.
