Added functionality to read file into a list stored in a HashMap with
the ability to store specific fashion/ set information in the future.
Should be able to search and display where an item is or should be in a
list relative to a few entries before and after in O(1) time.
Made how the main window will be laid out.  Changed the way that files
are read so that there will be a master list read first that will have
complete information on items, so an entry can be copied from there to
the user's list if it has it.  Added saving.  Before I can combine the
project, I need to figure out how to return the reference of an object
from its entry in the hashset after searching for the item.
