Feature flags for multi-module Kotlin Android projects.

Please visit [project website](https://mehow.io/laboratory/) for the full documentation and the [changelog](https://mehow.io/laboratory/changelog/).

## TLDR

Add Laboratory dependency to your project.

```groovy

repositories {

  mavenCentral()

}

dependencies {

  implementation "io.mehow.laboratory:laboratory:1.1.0"

}

```

Enable [default methods generation](https://blog.jetbrains.com/kotlin/2020/07/kotlin-1-4-m3-generating-default-methods-in-interfaces/).

```groovy

android {

  kotlinOptions {

    freeCompilerArgs += [

        "-Xjvm-default=all",

    ]

  }

}

```

Define your feature flags.

```kotlin

enum class AuthType : Feature {

  None,

  Fingerprint,

  Retina,

  Face;

  public override val defaultOption get() = Fingerprint

}

```

Start using them in the application.

```kotlin

suspend fun main() {

  // A high-level API for interaction with feature flags

  val laboratory = Laboratory.inMemory()

  // Set AuthType option to Fingerprint

  val success = laboratory.setOption(AuthType.Fingerprint)

  // Check what is the current option of AuthType

  val currentAuthType = laboratory.experiment()

  // Check if the current option of AuthType is equal to Face

  val isFaceAuth = laboratory.experimentIs(AuthType.Face)

  // Observe changes to the AuthType feature flag

  laboratory.observe()

      .onEach { option -> println("AuthType: $option") }

      .launchIn(GlobalScope)

}

```
