### Dependency
```gradle
implementation 'com.werb.statemachine:statemachine:0.0.1'
```
### Example
### Code
```kotlin
class StateMachineTest {
enum class State { Solid, Liquid, Gas }
enum class Transition { OnMelted, OnFroze, OnVaporized, OnCondensed }
private val stateMachine: StateMachine by lazy {
StateMachine().apply {
state(State.Solid) {
lastState?.apply {
println("I have been ${State.Solid} from $this")
} ?: with(State.Solid) {
println("I have been initialState with $this")
}
}
state(State.Liquid) {
lastState?.apply {
println("I have been ${State.Liquid} from $this")
} ?: with(State.Liquid) {
println("I have been initialState with $this")
}
}
state(State.Gas) {

println("I have been ${State.Gas} from $this")
} ?: with(State.Gas) {
println("I have been initialState with $this")
}
}
