Description: Creates a wrapper for the 'SuiteSparse' routines that
        execute the Takahashi equations. These equations compute the
        elements of the inverse of a sparse matrix at locations where
        the its Cholesky factor is structurally non-zero. The resulting
        matrix is known as a sparse inverse subset. Some helper
        functions are also implemented. Support for spam matrices is
        currently limited and will be implemented in the future. See
        Rue and Martino (2007) <doi:10.1016/j.jspi.2006.07.016> and
        Zammit-Mangion and Rougier (2018)
        <doi:10.1016/j.csda.2018.02.001> for the application of these
        equations to statistics.
