Add imports to examples in docs

[RKhatri93]

class DebugExampleApplication : ExampleApplication() {

  override fun onCreate() {
    super.onCreate()
    val analysisUploadListener = EventListener { event ->
      if (event is HeapAnalysisSucceeded) {
        val heapAnalysis = event.heapAnalysis
        TODO("Upload heap analysis to server")
      }
    }

    LeakCanary.config = LeakCanary.config.run {
      copy(eventListeners = eventListeners + analysisUploadListener)
    }
  }
}

where to import the LeakCanary?

[pyricau]

import leakcanary.LeakCanary

[RKhatri93]

Yes' I tried to import it from there and I got an error that 'config' has private access in the leak canary.LeakCanary'. And for the config any other changes needed?

[pyricau]

I don't know.
