SolveItem
specify whether the optimization problem is a satisfaction, minimization or maximization problem and/or expression to maximize/minnimize and/or annotation
rminizinc::Item -> SolveItem
.e: the expression to maximize or minimize
.st: the solve type
.ann: annotation of the solve type
.delete_flag: used to delete items
.e: the expression to maximize or minimize
.st: the solve type
.ann: annotation of the solve type
.delete_flag: used to delete items
new()create an instance of specify_problem class
