%% This function is called by a gen_server process 
%% whenever a previous callback returns {continue, Continue}. 
%% handle_continue/2 is invoked immediately after the previous callback, 
%% which makes it useful for performing work after initialization 
%% or for splitting the work in a callback in multiple steps, 
%% updating the process state along the way.
