Aspect that, when added to a parameterless void method, causes this method to be invoked after each property setter
or method (but not property getters), except those annotated with DoNotCheckInvariantsAttribute. The target method
must check any relevant condition and throw throw InvariantViolationException in case of violation.

Syntax
public sealed class InvariantAttribute : MethodAspect, IAspect<IMethod>, IAspect, ICompileTimeSerializable, ITemplateProvider, IEligible<IMethod>Remarks
The aspect defines a protected method VerifyInvariants that calls all invariant methods defined in the object including
in its base classes.
If the IsInvariantSuspensionSupported contract option is defined, the aspect also introduces
the protected methods SuspendInvariants, which allows to suspend the verification of invariants,
and AreInvariantsSuspended, which determines if the verification of invariants is currently suspended.
