/*

Done Features:

- Initiate General Structure
- Add WiFi Support
- Add MQTT Support both for Subscribing and Publishing
- Add JSON support to handle MQTT messaging
- Add File Handling
- Add Melody Class with functions to Play/Pause/Stop etc.
- Add Main BellEngine
- Add custom Relay Timings (saved on-board)
- Add RTC support
- Add Timekeeper class, with functions to track time and call schedules
- Add OTA Update Functionality
- Add global logger with Mode Selection (None, Error, Warning, Info, Debug)
- Add Captive Portal / WiFi HotSpot
- Add NTP Time Sync

ToDo Features:

- Add reset to Factory Defaults button
- Add manual Sync-Time (for No-Connectivity Setups)
- Add the ability to report the list of melodies
- Add the ability to report a month's ScheduleEntry
- Add the ability to report the free space in SPIFFS.
- Add Bluetooth support
- Add WiFi Direct AP Support
- Add PCB Temperature Sensor
- Counters and Statistics:
	- Counter for each bell (counts total times the bell ringed)
	- Counter per bell, beats/minute for reliability and thermal protection. Warranty Void scenario.
	- Counter per playback, to figure out which melody is the most played.
	- Counter of items per Scheduler
