Reorganize and add A-label structure
- Moving UniqueUnion.jar into the bin directory. - Created a data/A-label directory and added A-label conversions for each section's file. - Created a data/U-label directory but left this empty for now. Files at the root could be moved here, or some other action could be taken. - Added a final directory to store files with a unique union of Reserved Names. Added the unique union of A-labels to this directory.
