*
* IDEA: In gerneral store the current label name Go through the tree rooted at this label name and find all breaks if any
* break targets the current label name and not some previous one the label name can be removed from the break statement
* since it is the most recent break....TEST IT ON CASES AND SEE IF THIS IS TRUE THE JAVA LANGUAGE SAYS IT SHOULD BE TRUE
