LibreTasker is an event-based task performer, similar to Tasker.

This means that you can trigger Actions when events (filtered on input) occur, taking into consideration current state.

Supported events (and their conditions):
- Network:
	- Type: Wifi / Cellular / VPN
	- State: Connected / Disconnected
	- SSIDs: List of SSIDs when Type is Wifi
- DateTime (Similar to cron):
	- Month: List of ints
	- DOM: List of ints (Day of Month, 1-31)
	- DOW: List of ints (Day of Week, 1-7)
	- Hour: List of ints (00-24)
	- Minute: List of ints (00-59)
	- InvertHour: boolean (whether to invert the match on the 'Hour' field)
	- InvertMinute: boolean (whether to invert the match on the 'Minute' field)
- Screen:
	- OFF: boolean (whether to trigger on ON or OFF )
- SMS:
	- BodyRegex (String, Regex)
	- NameRegex (String, Regex)
	- Sender (String, matching Phone number exactly)
- PhoneCall:
	- Name (String)
	- Number (String)
	- State (String) { RINGING, IDLE }

There's an special event called 'State'. State takes a Key (String) and Value (Object). This gets triggered automatically when an Action with type 'State' **changes** its value.

Supported Actions (and their parameters):

- Toast:
	- String (text to display)
- Notification:
	- <String, String>, with 2 <K,V> Pairs: Title and Value, both must be non-null.
- Beep:
	- None (Plays the default notification ringtone)
- Volume:
	- <Int, Int> Stream (Ring, Alarm, Music, Notification, System), Volume in %
- State:
	- <String, Object>, set a state key to a value. Will trigger the 'State' special event if the value changed.


For example you could do something like:

- At 22:59 => Set Ringtone volume to 0%
- At 7:59 => Set Ringtone volume to 100%

or achieve the same thing with states:

- Between 22:59 and 7:59 => Set state 'sleepy' to true
- On 'sleepy' change to true => Set volume to 0% 
- On 'sleepy' change to false => Set volume to 100%
