Corrected some errors

-  Added some display functions in main
-  Made time class more stable (more const correctness, but not a high
priority right now)
-  Added pathcount to basic data that's loaded in snapshot_class.
-  Added color::set::greenblue()
-  added sorting algorithm for the basic data so that it can list times
from most recent to least recent
-  Other things...
Todo list update

* -  Start on snapshotList_class object
* -  Add delete function to delete a snapshot
* -  Add save function to save snapshot to file
* -  Write up the menus
