 * which returns valid serialiser that
 * can serialiser rs_item. You also need to implement an operator
 *
 * Also need to implement a function
 * 'bool operator =(YourRsItem& rs_itemL, YourRsItem& rs_temR)'
 * which allows this  function to test for equality between both parameters.
 * rs_temR is the result of deserialising the left operand (1st parameter).
 * not YourRsItem in specifier in about functions should be a derived type from RsItem
