e277586958 Complete rework of global math functions and NumTraits. 
* Now completely generic so all standard integer types (like char...) are supported.
** add unit test for that (integer_types).
* NumTraits does no longer inherit numeric_limits
* All math functions are now templated
* Better guard (static asserts) against using certain math functions on integer types.

9962c59b56 * implement the corner() API change: new methods topLeftCorner() etc 
* get rid of BlockReturnType: it was not needed, and code was not always using it consistently anyway
* add topRows(), leftCols(), bottomRows(), rightCols()
* add corners unit-test covering all of that
* adapt docs, expand "porting from eigen 2 to 3"
* adapt Eigen2Support

9a4a08da46 Creation of the Polynomials module with the following features: 
* convenient functions:
  - Horner and stabilized Horner evaluation
  - polynomial coefficients from a set of given roots
  - Cauchy bounds
* a QR based polynomial solver

307c428253 Move documentation of MatrixBase methods in MatrixFunctions to module page. 
I think that because MatrixFunctions is in unsupported/ and MatrixBase is
not, doxygen does not include the MatrixBase methods defined and documented
in the MatrixFunctions module with the other MatrixBase methods. This is a
kludge, but at least the documentation is not lost.

a7d085eb4e NonLinearOptimization : clean 'mode' handling from the old minpack code : 
* this is actually a boolean, not an int
* use a better name
* can be set at initialization time instead of bloating all methods signatures

4e389b195d Change MatrixFunction::separation() parameter from 0.01 to 0.1 . 
The latter is actually the value used in the literature.

67ce07ea83 matrix_function test: replace expm(A).inverse() by expm(-A) 
The latter is more stable. This fixes one of the issues with the test.
Also, make typedef's in MatrixFunctionReturnValue public; this is
necessary to get the test to compile.

afb9bf6281 use PlanarRotation<> instead of handmade givens rotation in cminpack code 
+ cleaning.
This results in some more memory being used, but not much.

91561cded4 use a plain matrix to store the upper triangular matrix 'R', instead 
of the "compact inside a vector" scheme used by fortran/minpack.
The most difficult part is to fix all related code. Tests pass.

1403cea087 fix a bug introduced between the cminpack version of Manolis Lourakis and 
the one from Frédéric Devernay.
Here, we want to compute the max over the column, the -1 is not needed in
fortran because indices start at 1, contrary to c/c++.

ee0e39284c Replace the qr factorization from (c)minpack (qrfac) by Eigen's own stuff. 
Results as checked by unit tests are very slightly worse, but not much.
