%% CT hook for logging of connections.
%%
%% HookOptions can be hardcoded in the test suite:
%%
%% suite() ->
%% [{ct_hooks, [{cth_conn_log,
%% [{ct_netconfc:conn_mod(),ct_netconfc:hook_options()}]}]}].
%%
%% or specified in a configuration file:
%%
%% {ct_conn_log,[{ct_netconfc:conn_mod(),ct_netconfc:hook_options()}]}.
%%
%% The conn_mod() is the common test module implementing the protocol,
%% e.g. ct_netconfc, ct_telnet, etc. This module must log by calling
%%
%% error_logger:info_report(ConnLogInfo,Data).
%% ConnLogInfo = #conn_log{} | {ct_connection,Action,ConnName}
%% Action = open | close | send | recv | term()
%% ConnName = atom() - The 'KeyOrName' argument used when opening the connection
%%
%% ct_conn_log_h will print to html log or separate file (depending on
%% log_type() option). conn_mod() must implement and export
%%
%% format_data(log_type(), Data).
%%
%% If logging to separate file, ct_conn_log_h will also log error
%% reports which are witten like this:
%%
%% error_logger:error_report([{ct_connection,ConnName} | Report]).
