mk_coarse_fine_mapping

MK_COARSE_FINE_MAPPING: create a mapping matrix from coarse to fine FEM
 [c2f,out]= mk_coarse_fine_mapping( f_mdl, c_mdl, opt );

 C2F_ij is the fraction of f_mdl element i which is
   contained in c_mdl element j. This is used to map
   from data on the reconstruction model (c_mdl) to
   the forward model f_mdl as 
      elem_data_fine = Mapping*elem_data_coase
 OUT_i is the fraction of f_mdl element i which is not
   contained in any c_mdl element.
  
 Parameters:
    c_mdl is coarse fwd_model
    f_mdl is fine fwd_model
    opt   is option structure (optional, see below)

 This function is a compatibility wrapper. The actual calculations are
 carried out by either MK_ANALYTIC_C2F or MK_APPROX_C2F (the older
 method). 

 To set a specific implementation use
    eidors_default('set','mk_coarse_fine_mapping','mk_approx_c2f');

 To query current implementation use
    eidors_default('get','mk_coarse_fine_mapping');

 NOTE that MK_ANALYTIC_C2F accepts an optional third argument whereas
 MK_APPROXIMATE_C2F does not.
