Returns a Boolean value that indicates whether the receiver is greater than or equal to another given object.
The object with which to compare the receiver.
YES if the receiver is greater than or equal to object, otherwise NO.
During the evaluation of an NSWhoseSpecifier object that contains a test whose operator is NSGreaterThanOrEqualToComparison, anisGreaterThanOrEqualTo: message may be sent to each potentially specified object, if the potentially specified object does not implement a scriptingIsGreaterThanOrEqualTo: method and the object being tested against does not implement a scriptingIsLessThan: method.
The default implementation for this method provided by NSObject returns YES if a compare: message sent to the same object would return NSOrderedSame or NSOrderedDescending.
