Modified files:
	src            : Recurrence.defs.hh rr_solver.cc util.cc util.hh 

Log message:
	The functions `solve_constant_coeff_order_2()' and
	`solve_constant_coeff_order_2()' are now private functions
	of the class Recurrence.
	
	Renamed `domain_recurrence()' into `biggest_positive_int_zero()':
	improved it and moved it in the file `util.{hh, cc}.
	
	Added the check to find the first initial condition also
	for linear recurrences with constant coefficients.
	
	Fixed some bugs in the lower bounds of the symbolic sum.
