/**
* Annotation used for turning off Groovy's auto visibility conventions.
* By default, Groovy automatically turns package protected fields into properties
* and makes package protected methods, constructors and classes public.
* This annotation allows this feature to be turned
* off and revert back to Java behavior if needed.
*
* Place it on classes, fields, constructors or methods of interest as follows:
* <pre>
* {@code @}PackageScope class Bar { // package protected
* {@code @}PackageScope int field // package protected; not a property
* {@code @}PackageScope method(){} // package protected
* }
* </pre>
* or for greater control, at the class level with one or more
* <code>PackageScopeTarget</code> values:
* <pre>
* import static groovy.transform.PackageScopeTarget.*
* {@code @}PackageScope([CLASS, FIELDS])
* class Foo { // class will have package protected scope
* int field1, field2 // both package protected
* def method(){} // public
* }
* {@code @}PackageScope(METHODS)
* class Bar { // public
* int field // treated as a property
* def method1(){} // package protected
* def method2(){} // package protected
* }
* </pre>
*
* This transformation is not frequently needed but can be useful in certain testing scenarios
* or when using a third-party library or framework which relies upon package scoping.
