/**
* A sequence of validation groups.
*
* When validating a group sequence, each group will only be validated if all
* of the previous groups in the sequence succeeded. For example:
*
* $validator->validate($address, null, new GroupSequence('Basic', 'Strict'));
*
* In the first step, all constraints that belong to the group "Basic" will be
* validated. If none of the constraints fail, the validator will then validate
* the constraints in group "Strict". This is useful, for example, if "Strict"
* contains expensive checks that require a lot of CPU or slow, external
* services. You usually don't want to run expensive checks if any of the cheap
* checks fail.
*
* When adding metadata to a class, you can override the "Default" group of
* that class with a group sequence:
*
* /**
* * @GroupSequence({"Address", "Strict"})
* *\/
* class Address
* {
* // ...
* }
*
* Whenever you validate that object in the "Default" group, the group sequence
* will be validated:
*
* $validator->validate($address);
*
* If you want to execute the constraints of the "Default" group for a class
* with an overridden default group, pass the class name as group name instead:
*
* $validator->validate($address, null, "Address")
*
* @Annotation
* @Target({"CLASS", "ANNOTATION"})
