* added innerSize / outerSize functions to MatrixBase

Browse Source 
* added complete implementation of sparse matrix product
  (with a little glue in Eigen/Core)
* added an exhaustive bench of sparse products including GMM++ and MTL4
  => Eigen outperforms in all transposed/density configurations !
