interp_form_t	create_interpolation (const emInterpArg &arg, vector< emInterpArg > *nonlocal=NULL, bool all_nonlocal=false)
	returns the coefficients of field interpolation adds non-local (unresolved) requests to nonlocal (if it is not NULL)

int	get_out_data_max_count () const
	gets the maximal possible number of output points for a contour

int	get_out_data_index (const contour_it &cnti, indtype ind, valtype coeff, int check=0) const
	gets the data index and coefficients of output (central) updated data points as distributed from contour center puts the indicies and coefficients into corresponding arrayes provided it is assumed that the pointers have space at least for get_out_data_max_count() entries if check==1 performs data index memory range validity check
