combineLatestCompat (for java users) and combineLatest(inline/reified)

I was missing these two fellows :). Below some example usage:

private val name = MutableLiveData<String>()
private val email = MutableLiveData<String>()
private val age = MutableLiveData<Int>()
private val money = MutableLiveData<Double>()

val user: LiveData<User> = combineLatest<Any, User>(name, email, age, money) { latestResult ->
    User(name = latestResult[0] as String,
            email = latestResult[1] as? String,
            age = latestResult[2] as Int,
            money = latestResult[3] as Double,
}

data class User(val name: String, val email: String?, val age: Int, val money: Double)

init {
    name.value = "snuffix"
    email.value = null
    age.value = 20
    money.value = 20.0
}

I think having an Any? as the receiver and force-unwrapping it is not a good idea, specially in Kotlin world. (Similar issue in RxKotlin here)
