_D_e_s_c_r_i_p_t_i_o_n:

     Performs the inverse DWT for 'wd3D.object', i.e. 3D DWT objects.

_U_s_a_g_e:

     wr3D(obj)

_A_r_g_u_m_e_n_t_s:

     obj: A 'wd3D.object' 3D DWT object as returned by 'wd3D'.  

_D_e_t_a_i_l_s:

     The code implements a 3D version of Mallat's inverse pyramid
     algorithm.

_V_a_l_u_e:

     A 3D array containing the inverse 3D DWT of obj.

     #
     # Now let's take the object generated by the last stage in the EXAMPLES
     # section of threshold.wd3D and invert it!
     #
     #testwr <- wr3D(testwd3DT)
     #
     # You'll find that testwr is an array of dimension 8x8x8!
