- 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.
