Spectral Decomposition of Affiliation Matrix After Symmetric Normalization

1	.adj_eigen_norm(x, k, check_dang, check_sym, set_diag_zero)

`x`	sparse affiliation matrix
`k`	number of (largest) eigenpairs to extract
`check_dang`	check whether there are dangling nodes
`check_sym`	check whether `x` is symmetric
`set_diag_zero`	if `true`, sets the diagonals of `x` to zero

the normalized adjacency matrix is D^{-1/2}AD^{-1/2}, where D^{-1/2} is the square-root of the diagonal matrix containing the degrees of A.

returns the k largest eigenvalue-eigen vector pairs of the normalized affiliation matrix
