/**
This script can merge two multi dimensional associative array/objects in javascript by comparing given object with its reference and 
will remove additional given keys, adding missed parameteres and also validating values without overhead. Also it will return the default values if no input presented with re-usable reference!
Tested on IE8 and greater.
