SATDBailiff-1.1

• Added functionality for mapping SATD Instances located above method signatures to the associated proceeding method.
• Implemented cross-file tracking. This occurs when SATD is removed in one file during the same commit when it is added to another. In this case, we want to maintain an instance reference (in the form of a child-parent relationship to allow for multiple instances with single parents in the case of SATD proliferation) between the two (or more) instances.
