CRUD operations for events
events are DLSU org events. They may have the following data:

{
      name: String,
      org_id: String, // which org the event belongs to
      date: String, // date and time the event will be held
      announce: Boolean, // if the event should be publicly displayed on the website (for future use)
      id_key: String, // this is what we will use for checking the IDs in the CSV data, e.g. what field contains 121xxxxx
      data: [] // this will contain the CSV data
}
