Detailed Description

Define an NSArray.Operator for the key sort.

This allows for key value paths like:

1. myArray.valueForKey("@sort.firstName");
2. myArray.valueForKey("@sort.lastName,firstName.length");

Which in the first case would return myArray sorted ascending by first name and the second case by lastName and then by the length() of the firstName. Due to the way the sort key arguments are written, this key cannot occur anywhere except at the very end of the keypath.
