_D_e_s_c_r_i_p_t_i_o_n:

     The function returns a matrix where each row is a (un)balanced
     permutation of the input twosample class labels.

_U_s_a_g_e:

     twilight.permute.unpair(v, m, bal = TRUE)

_A_r_g_u_m_e_n_t_s:

       v: A binary vector representing class labels in original order. 

       m: A numerical value giving the number of permutations. 

     bal: Logical value. Results in balanced or unbalanced
          permutations. 

_V_a_l_u_e:

     Returns a matrix where each row contains one permuted vector of
     class labels. Note that even for balanced permutations, the first
     row always contains the original vector.
