/**
|
|
This category adds diffing comparisons similar to adding the object into an NSSet, where the object's isEqual: method
|
|
drives the uniqueness of the object.
|
|
|
|
For instance, an NSString's isEqual: will compare the value of the strings. So if you were to diff @"cat" and @"cat"
|
|
each object would have the same diff identifier.
|
|
|
|
However objects that don't implement a custom isEqual: (e.g. the NSObject base class), the diff will default to simple
|
|
pointer comparisons to establish uniqueness.
