ObjectEquality
in
An object implementing this interface can determine if it equals any other value.
Strict comparison ($a === $b) does not work on different instances of objects that represent the same value.
Regular comparison ($a == $b) is possible, but you need to remember to use it on object comparison, but not on
other value types which is confusing. By implementing this interface on the objects that require comparison you can
use $a->equals($b) and you have all the control.

}
