var obj = {

  complexProperty: {
    child: 126
  }
};

var map = {
  flattern: 'complexProperty.child',
  explode: {
    child: 'simpleProperty'
  }
};

var objMap = new MapObjLib(map);
objMap.map(obj, function(error, result) {
  /* result == {
    flattern: 126,
    explode: {
      child: 42
    }
