Simple Tkinter GUI for sentimental phrase dataset creation

""" A simple Tkinter Gui for creating a Sentimental Dataset.
    The output format is {'phrase': 'classification', ...}
    The dictionaries are loaded from and persisted with cPickle.
    The dataset dictionary can be saved at any time
    As can the depleted phrase dictionary.
    The dictionaries don't autosave so use the menubar :)
