612350e3f8 * Added a generic *redux* mini framework allowing custom redux operations
as well as partial redux (vertical or horizontal redux).
   Includes shortcuts for: sum, minCoeff and maxCoeff.
   There is no shortcut for the partial redux.

 * Added a generic *visitor* mini framework. A visitor is a custom object
   sequentially applied on each coefficient with knowledge of its value and
   coordinates.
   It is currentlly used to implement minCoeff(int*,int*) and maxCoeff(int*,int*).
   findBiggestCoeff is now a shortcut for "this->cwiseAbs().maxCoeff(i,j)"

 * Added coeff-wise min and max.
 * fixed an issue with ei_pow(int,int) and gcc < 4.3 or ICC

fb3438e609 - expand MathFunctions.h to provide more functions, like exp, log...
- add cwiseExp(), cwiseLog()...
   --> for example, doing a gamma-correction on a bitmap image stored as
       an array of floats is a simple matter of:
         Eigen::Map<VectorXf> m = VectorXf::map(bitmap,size);
         m = m.cwisePow(gamma);
- apidoc improvements, reorganization of the \name's
- remove obsolete examples
- remove EIGEN_ALWAYS_INLINE on lazyProduct(), it seems useless.

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