api.js

// Inspired by 'alexismenest' capstone 'mockAPI' logic.
// fetchAPI accepts a JavaScript Date object.
// fetchAPI returns a list of randomly generated available times.
// The times are between 15:00 and 23:30.
// The list always begins with "--- Select a Time---"
// I found this useful for debugging.
// 
// submitAPI always returns 'true'.
