/**
* Utility method to obtain annotations of a specific type from the supplied PsiModifierListOwner.
* For optimization reasons, this method only looks at elements of type java.lang.String.
*
* <p>The parameter <code>allowIndirect</code> determines if the method should look for indirect
* annotations, i.e. annotations which have themselves been annotated by the supplied annotation
* name. Currently, this only allows one level of indirection and returns an array of
* [base-annotation, indirect annotation]
*
* <p>The <code>annotationName</code> parameter is a pair of the target annotation class' fully
* qualified name as a String and as a Set. This is done for performance reasons because the Set
* is required by the {@link com.intellij.codeInsight.AnnotationUtil} utility class and allows to
* avoid unnecessary object constructions.
