This code was taken from csa.irde.to. It was made optimized and usable for out project. We created the user interface and allow for creating and reading of files. We have also incorporated a functionality that check two files for equivalency. This does the quivalency check in a way that would ensure that the same data data is always recoginzed as the same. -This code was taken from csa.irde.to.　It was made optimized and usable for out project.　We created the user interface and allow for creating and reading of files.　We have also incorporated a functionality that check two files for　equivalency.　This does the quivalency check in a way that would ensure that the same data data is always recoginzed as the same.
