Replace all direct references to linked objects with stubs.
This method is needed tyo avoid memory exhaustion in case when
there is a large numebr of objectys in databasse, mutually

Replace references to elements with direct references.
It will impove spped of manipulations with links, but it can cause
recursive loading in memory large number of objects and as a result - memory
overflow, because garabge collector will not be able to collect them
