Late Initialization (#3)

The starter code provides:

data class Generator(val id: Int)

class Turbine(val id: Int) {
  private lateinit var _generator: Generator
  val generator: Generator
...

Add a get() for generator that checks to see if _generator has been initialized, and if not initializes it before returning _generator. Add a toString() that starts with "Generator $id running: " and then indicates if the generator is running.

The starter code provides:

class PowerPlant(nTurbines: Int = 4) {
  private val turbines: List<Turbine> =
...

Finish the initialization for turbines, then add fun generator(number: Int): Generator which checks to make sure number is in range, then returns the desired generator. Finally, add a status() member function that uses forEach to show the status of each generator in the PowerPlant. The code in main() tests your solution.
