	New function to set the comparison function for the sort.

	* ov.cc (octave_value::octave_value (const ArrayN<char>&, bool)):
	New Constructor .

	* ov.h (octave_value::octave_value (const ArrayN<char>&, bool)):
	Declaration.

	* DLD-FUNCTIONS/sort.cc (sortmode): New enum to define direction of
	sort.
	(template <class T> class vec_index): New class to contain values and
	index for indexed sorts, replacing all previous struct versions. 
	Instantiate for double, Complex, char and octave_value.
	(template <class T> static octave_value_list mx_sort (ArrayN<T> &, int,
	sortmode)): New templated version of mx_sort replacing all previous
	versions, but specific to non indexed sorts. Instantiate for char
	and double if not IEEE754.
	(template <> static octave_value_list mx_sort (ArrayN<double> &, 
	int, sortmode)): Specialized function of mx_sort of IEEE754.
	(template <class T> static octave_value_list mx_sort_indexed 
	(ArrayN<T> &, int, sortmode)): New templated version of mx_sort 
	for indexed sorts. Instantiate for double, Complex, char and 
	octave_value.
	(ascending_compare, descending_compare): Comparison functions
	for double, char, vec_index<double> *, vec_index<Complex> *,
	vec_index<char> *, vec_index<octave_value>. Fix Complex comparison
	operator to sort by arg of values if absolute values are equal.
	(Fsort): Update docs for new mode argument and for sorting of 
	strings and cell arrays of strings. Implement mode argument to
	define ascending and descending sorts. Include sorting of cell
	arrays of strings. Adapt for new templated versions of the mx_sort
	function.
