     * This class allows the user to write a little about their day or week. Their is no alarm
     * to remind them to do this. This is completely up to the user if she/he wants to log something
     * that may be helpful to remember or reflect on what changed their mood. This way the user
     * can keep track of and maybe start finding patterns in their stress levels based on daily
     * activity.
     *
     * This actually uses 2 file locations in saved preferences one to save all the names of the
     * files for the spinner. The other uses the file name to store the text data from the journal
     * itself.
     *
     * Also the spinner needs to know how many files it is looking to fill the spinner with so
     * their is a shared pref to keep track of the number of times the save button was hit.
     *                                                  -Thomas Wolf
