Support for registering multiple timetables

[Copilot]

Refactors the data structure to support an arbitrary number of train schedules instead of a single weekday/holiday pair.

Data Structure

• TrainScheduleData.mc.example: Replaced weekday_table/holiday_table with schedules array containing objects with title, weekday, and holiday keys

var schedules = [
    {
        "title" => "Commuting - Outbound (Home → Office)",
        "weekday" => [[514,0],[628,1],[655,0]],
        "holiday" => [[614,0],[738,1],[855,0]]
    },
    // ... additional schedules
];

View Updates

• TrainScheduleFinderView.mc: Added schedule navigation (nextSchedule(), previousSchedule()) and title display

Input Handling

• TrainScheduleFinderDelegate.mc: New delegate handles swipe up/down to cycle through schedules
• TrainScheduleFinderApp.mc: Wired delegate to view

Documentation

• README.md: Updated to reflect new data format

example

// Each schedule contains: title, weekday, holiday
// Time entries keep the existing format: [hhmm(int), type(int)]
// type: 0 = local, 1 = express, 2 = special

module TrainScheduleData {
    var schedules = [
        {
            title: "Commuting - Outbound (Home → Office)",
            weekday: [
