Detailed Description

Define an NSArray.Operator for the key isEmpty.

This allows for key value paths like:

myArray.valueForKey("@isEmpty");

Which in this case would return true if the myArray.count() == 0, or false if it is not. This operator always ends computation. Any keypath following the isEmpty operator is simply ignored.
