Improve performance when swiping to left & to the right.

@duyluonglc I see on the iOS simulator, when swiping in either direction, sometimes I see blank screens. It looks to me like this is because we are using the onMomentumScrollEnd and setState to set the current date.

I think we might be able to achieve the same result without using setState and instead have VirtualizedList 'ask' for the items we wish to render for the given day/index in the calendar.

What do you think @duyluonglc ?

sorry @joshyhargreaves I'm too busy with projects. I saw the delay issue, and sometime it shows blank screen. But have no solution. Let try your way and let me know result

I will do @duyluonglc!
