_D_e_s_c_r_i_p_t_i_o_n:

     This function changes the order of the QTL in a QTL object.

_U_s_a_g_e:

     reorderqtl(qtl, neworder)

_A_r_g_u_m_e_n_t_s:

     qtl: A qtl object, as created by 'makeqtl'.

neworder: A vector containing the positive integers up to the number of
          QTL in 'qtl', indicating the new order for the QTL.

_D_e_t_a_i_l_s:

     Everything in the input 'qtl' is reordered except the 'altname'
     component, which contains names of the form 'Q1', 'Q2', etc.

_V_a_l_u_e:

     The input 'qtl' object, with the loci reordered.
