    @brief describes a homography 
    
    A HMatrixBase describes a homography (mapping between two planes) between 
    homogenous 2D coordinates by a 3x3 Matrix.
    It is derived from Matrix3x3.
    Only implementation very specific to HMatrixBase (and not valid for general
    3x3 matrices, e.g. like decomposition) 
    should be implemented here.
