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

     Lets the tree ref the node.  This is an optional method for models
     to implement.  To be more specific, models may ignore this call as
     it exists primarily for performance reasons.

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

     gtkTreeModelRefNode(object, iter)

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

'object': ['GtkTreeModel']  A 'GtkTreeModel'.

  'iter': ['GtkTreeIter']  The 'GtkTreeIter'.

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

     This function is primarily meant as a way for views to let caching
     model  know when nodes are being displayed (and hence, whether or
     not to cache that node.)  For example, a file-system based model
     would not want to keep the entire file-hierarchy in memory, just
     the sections that are currently being displayed by every current
     view.

     A model should be expected to be able to get an iter independent
     of its reffed state.
