• Fix error where transitioning boolean was left true after state change had completed.

2.0.0

• StateMachine constructor now expects an options Object, i.e super(opts).
• opts.initialTransitions is required by the super constructor. This replaces $next requirement.
• Rename IStateDeclaration to PartialProperties.
• Remove support for individual class fields in favour of a props container.
• opts.props is required by the super constructor. This replaces rememberInitState requirement.
• Add Properties and ValidStates generics, i.e StateMachine<Properties, ValidStates>
• Disable console.error logs by default. Can be enabled via opts.logging.
• Make transitTo and others type safe using ValidStates generic.
• Return typed errors from transitTo. These use the TransitionError type.
• Change signature of onEnter callbacks to (prevState: string ...args: Array<any>) => void
• Change signature of onLeave callbacks to (targetState: string) => void
• Fix issue #1.
