EXPRESS Heading Query function get_changes(                 search_criteria,                  timestamp : STRING;                  language_codes,                   context_guids	: LIST OF STRING): IfdChanges;

The function investigate target IFD population collecting shallow info about all changed after specified date/time concepts.

Input:
 * string search_criteria- string pattern to apply to the concept names to filter them. The pattern can include the whole interesting name or its part (letters are case insensitive) and a number or matching characters;
 * string timestamp _priority - date/tiem stamp in format ‘YYYY.MM.DD hh:mm:ss’ specifying a moment to search for changes after it;
 * string language_codes – list of languages specified by their codes to limit the changed concepts representation (normally it shall be all languages defined in IFD population local copy);
 * string context_guids– list of context global unique ids – domains of relationships

Return:
 * IfdChanges[] - Structure that represents all updated (added) concepts in target IFD population.
