Package containing easy implamentation of Finite State Machine using Combine

TODO:

[ ] Improved logging control

Example usage

enum TestEvents: EventProtocol {
  case event1, event2
}

enum TestStates: StateProtocol {
  case initial, step1, step2, step1Alt, finish
}

let stateMachine = StateMachine<TestEvents, TestStates>(with: .initial)
let transition = StateMachineTransition<TestEvents, TestStates>(event: .event1, from: .initial, to: .finish)
try? stateMachine.append(transition: transition)
stateMachine.transitionQueue.waitUntilAllOperationsAreFinished()
XCTAssertEqual(stateMachine.state.value, .initial)

stateMachine.event.send(.event1)
stateMachine.transitionQueue.waitUntilAllOperationsAreFinished()
XCTAssertEqual(stateMachine.state.value, .finish)

Check tests for more usage exmples
