b3268a6e2f -merge patch from Gael Guennebaud adding NumTraits for long long
and long double.
-define scalar-multiple operators only for the current Scalar type;
 thanks to Gael for expaining how to make the compiler understand
 when automatic casting is needed.
-take ScalarMultiple take only 1 template param, again.
 We lose some flexibility especially when dealing with complex numbers,
 but we gain a lot of extensibility to new scalar types.

aa8e2bcbde Patch by Gael Guennebaud:
Rework the matrix storage to ensure optimal sizeof in all cases, while
keeping the decoupling of matrix sizes versus storage sizes.
Also fixing (recently introduced) bugs caused by unwanted
reallocations of the buffers.

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

c67e717404 alpha 3.1. in this commit:
- finally get the Eval stuff right. get back to having Eval as
  a subclass of Matrix with limited functionality, and then,
  add a typedef MatrixType to get the actual matrix type.
- add swap(), findBiggestCoeff()
- bugfix by Ramon in Transpose
- new demo: doc/echelon.cpp

9c9a42cc49 Eval is now implemented like the other expression types, it no longer
inherits Matrix. Remove the typedefs I added in Matrix.

e20aceb6eb cleanup in Eval; instead introduce convenient typedefs in Matrix
for naming special related matrix types: RowType, ColumnType,
BlockType

6ce996f219 big improvement of the block-manipulation API
- reduction of sizeof(Block) for vector types
- variants of block() and fixedBlock() for vector blocks
- convenience methods start() and end() for vectors
- convenience method corner() for matrices

95dc68dc86 renaming:
Block -> FixedBlock
DynBlock -> Block
indeed, previous commit solves the main issue with DynBlock so
is should now be the more commonly used one.

89a134ba0b big architecture change dissociating "actual" dimensions from "maximum possible"
dimension. The advantage is that evaluating a dynamic-sized block in a fixed-size
matrix no longer causes a dynamic memory allocation. Other new thing:
IntAtRunTimeIfDynamic allows storing an integer at zero cost if it is known at
compile time.

e092cbc75c -add set...() methods and their documentation; remove Generic
-use row-major traversal when the number of columns is fixed
 and the number of rows is dynamic

47d354924b revert most of previous commit. It really is better to forbid default
constructor for dynamic-size matrices. Now why do I feel like a beheaded
chicken running around?

b036eca902 Revert to allowing default Matrix constructor even for dynamic size (which is
then set to 1). Discussion with jonasp made me remember why we did so in Eigen1.
Also add default constructor to Eval

8ba3055447 Ready for alpha2 release.
- complete documentation
- add TODO
- update copyright years

5111ace0d6 move default parameter values from function definition to function declaration.
doxygen likes it and this fixes compilation on ICC.

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

aaf889e72b remove all the _Order mechanics, now we are always traversing matrices in
column-major order, even if storage is row-major. Benchmark showed that adapting
the traversal order to the storage order brought no benefit.

Also do some cleanup after Gael's big patch.

d1d55e67e9 - make MatrixBase and all expressions aware of their preferred traversal order.
Honor this preference in operator=.
- add several methods to the API
- rework API for diagonal matrices
- add benchmarking code

42f6590bb2 cleanup: remove copy contructors when the compiler is able to generate a satisfactory
default copy constructor; remove useless static_cast's; some misc cleanup.

86220784b6 part 2 of the reorganization. Benefits/changes:
1) Eigen2 co-installable with Eigen1 without conflict, without affecting programs including either.
2) #include<Eigen/Core> without the .h without conflict with the Core/ directory
3) Uniformize coding style of the CMakeLists.

e7bdbe2e6a matrix storage order can now also be row-dominant (choosable for each matrix separately)
map() moves from MatrixBase to Matrix

6b9370e0f0 more changes in ScalarMultiple, reintroduce FloatingPoint in NumTraits, improve
examples

05a49547e1 in ScalarMultiple, make the factor type independent from the matrix scalar type.
This is an optimization for complex matrices, allowing to do only a real multiplication
when a complex multiplication is not needed, e.g. in normalized().

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.

3cd2a125b2 - rework the coefficients API
- make vectors use a separate loop unroller, so that copying a
row-vector into a col-vector is now possible
- add much more documentation
- misc improvements

e937583655 everything works, make now runs doxygen once and only once, after all
the required files have been generated.

c38156a217 now we also have a examples/ directory for self-contained examples,
and this is already used to document DynBlock

a52c74095f rename src/ to Eigen/ so that we're able to #include<Eigen/Core.h>
in the examples instead of ugly things like #include"../../src/Core.h"
