Checks whether the annotated date is in the past / future

Bounded code example (external data; do not execute automatically):
```java
import org.hibernate.validator.constraints.Past;
import org.hibernate.validator.constraints.Future;

public class DoctorVisit {

   //Constraint: Birthdate must be in the past
   @Past
   private Date birthDate;

   public Date getBirthDate() {
      return birthDate;
   }

   public void setBirthDate(Date birthDate) {
      this.birthDate = birthDate;
   }

   //Constraint: Schedule visit date must be in the future
   @Future
   private String scheduledVisitDate;

   public String getScheduledVisitDate() {
      return scheduledVisitDate;
   }

   public void setScheduledVisitDate(String scheduledVisitDate) {
      this.scheduledVisitDate = scheduledVisitDate;
   }

...
}
```

Bounded code example (external data; do not execute automatically):
