        * added JavaScript scope property to track an object body,
        * process keywords as identifiers, if they were used as name function or object member,
        *'catch' and finally' were added to ignore list, so they would not normalized as function identifiers,
        * added unit tests to cover changes
        * 'function' isn't supporting as object member because of anonymous function peculiarities
