  // example: currentSecretPath is a array so when you try to .push() to it
  // it will modify the object that was getted from this class
  // then when you try to access it again, there will be a different object.
  // I guess you could make another class that emulates a Array or Map 
  // by using a bunch of functions and modifying localStorage in order to remove some of
  // the clunkyness of this approach, but for now, this works.
