-/**
- * \brief Performs a symbolic factorization on a panel of columns [jcol, jcol+w)
- * 
- * A supernode representative is the last column of a supernode.
- * The nonzeros in U[*,j] are segments that end at supernodes representatives
- * 
- * The routine returns a list of the supernodal representatives 
- * in topological order of the dfs that generates them. This list is 
- * a superset of the topological order of each individual column within 
- * the panel.
- * The location of the first nonzero in each supernodal segment 
- * (supernodal entry location) is also returned. Each column has 
- * a separate list for this purpose. 
- * 
- * Two markers arrays are used for dfs :
- *    marker[i] == jj, if i was visited during dfs of current column jj;
- *    marker1[i] >= jcol, if i was visited by earlier columns in this panel; 
- * 
- * \param[in] m number of rows in the matrix
- * \param[in] w Panel size
- * \param[in] jcol Starting  column of the panel
- * \param[in] A Input matrix in column-major storage
- * \param[in] perm_r Row permutation
- * \param[out] nseg Number of U segments
- * \param[out] dense Accumulate the column vectors of the panel
- * \param[out] panel_lsub Subscripts of the row in the panel 
- * \param[out] segrep Segment representative i.e first nonzero row of each segment
- * \param[out] repfnz First nonzero location in each row
- * \param[out] xprune The pruned elimination tree
- * \param[out] marker work vector
- * \param  parent The elimination tree
- * \param xplore work vector
- * \param glu The global data structure
