Added JSON examples to git
ArrayList of conference days created

/src/org/osuosl/ocw/Schedule.java: As events are pulled from the JSON their dates are added without repetition to a globally declared ArrayList. The method now() uses this ArrayList to determine if the current times before or after the conference, in either of these cases the view is set to the first day of the conference. This method already existed I just simply refactored it to use the ArrayList.
next and previous methods use ArrayList

/src/org/osuosl/ocw/Schedule.java: next and previous look for the current date in the ArrayList of days and then set the current date to the next or previous date in the ArrayList.

/JSON/schedule.json: repeated an event on extra days for multiple day testing.
Unique ids for repeated events

/JSON/schedule.json: forget to change the ids of the repeated events for testing.
Old data_format for json
