Kotlin extension to import a Kodein module only if it exists

ImportIfExists.kt

/**
 * Import a Kodein module if it exists. We're not catching any exceptions in this method so it will
 * fail fast. If a Kodein module doesn't import, the app will probably crash soon after this method
 * executes anyway. If the app crashes here, it will be easier to debug.
