* Purpose:                                                                                        *
*    To preserve the attributes of identifiers. Each object is a row in the Symbol Table.         *
* Data variables (private):                                                                       * 
*    1) 'isInit' (bool) - tells if a variable was initialized.                                    *
*    2) 'intValue' (long long) - keeps the value that corresponds to identifier.                  *
* Functions (public):                                                                             *
*    1) Constructor.                                                                              *
*    2) 'isInitialized' -  returns 'true' if variable was initialized and false otherwise (bool). *
*    3) 'getValue' - returns the value of the variable (long long).                               *
*    4) 'initialize' - updates that the variable was initialized (void).                          *
*    5) 'setValue' - changes the value of the variable (void).                                    *
