Randolf is busy 24/7 instantiating your kotlin data classes with autogenerated values
this is how it looks in action.
data class Group(val name: String)
data class User(val firstName:String, val name:String, val age: Int, val lat:Double, val long:Double, val group:Group)
print(Randolf.create<User>())
=> User(firstName=xdUpnBjqLMgOmb[U25ym, name=`6Eb2K4uO4;pv:i;V@AI, age=-776962503, lat=0.8399883812751676, long=0.40143311870843756, group=Group(name=Q\M1^ZIphuEZwlC<43SX))
