to Do

invitees not saving timeline refresh

event w/o dates = not saved

invites array in inviteVC

deconnect invite button from follow

click on invite button in Cell (button changes)

create segue to access invites in inviteVC segue- inviteVC -> VC append user to invites cell > VC appends user to database invited events>user>events

inviteVC in viewwillappear display database invites

timeline displays indicator turns diff color

if invites not sent then display edit vc

if invitee = true, then display

invited events

invitees for each event - event > host uid > event id > invitees > user.uid

invited events > user.uid > event id : bool

how to connect date to cell

    if let cellState = calendarView.cellStatus(at: point) {
        let date = cellState.date


/// Select a date-cell range
/// - Parameter startDate: Date to start the selection from
/// - Parameter endDate: Date to end the selection from
/// - Parameter triggerDidSelectDelegate: Triggers the delegate
///   function only if the value is set to true.
/// Sometimes it is necessary to setup some dates without triggereing
/// the delegate e.g. For instance, when youre initally setting up data
/// in your viewDidLoad
/// - Parameter keepSelectionIfMultiSelectionAllowed: This is only
///   applicable in allowedMultiSelection = true.
/// This overrides the default toggle behavior of selection.
/// If true, selected cells will remain selected.
public func selectDates(_ dates: [Date], triggerSelectionDelegate: Bool = true, keepSelectionIfMultiSelectionAllowed: Bool = false) {
    if dates.isEmpty { return }
    if (!isCalendarLayoutLoaded || isReloadDataInProgress) {
        // If the calendar is not yet fully loaded.
        // Add the task to the delayed queue
        delayedExecutionClosure.append {[unowned self] in
            self.selectDates(dates,
                             triggerSelectionDelegate: triggerSelectionDelegate,
                             keepSelectionIfMultiSelectionAllowed: keepSelectionIfMultiSelectionAllowed)
        }
        return
    }

everytime go back and edit, pre-selected dates re-merged

invitees not displaying on edit

new events not showing on table until rebuilt

only events w/dates are read reload get data on viewWillAppear, then reload table

invitees w/o dates or invitees not read, set to []

                self.inviteesUser.append()

segue animations

can't use longpress select more than once

cellState of cell of dateSelected true that it is selected

for date in datesChosen { date.cellState.isSelected = true }

            //count number of occurance 
            
            //create new array of all merged dates,, use this array here
                //create users. add users to indiv events.
            
            var counts: [Date: Int] = [:]
            for date in datesChosen {
                counts[date] = (counts[date] ?? 0) + 1
            }
            
            //sort array by count value, then display only top three
            print(counts)  // "[BAR: 1, FOOBAR: 1, FOO: 2]"
            for (key, value) in counts {
                print("\(value) of people prefer the \(key) date")
            }
