tcplConfSave()tcplConf changes options to set the tcpl-specific options, 
most importantly to configure the connection to the tcpl databases. 
tcplConf will only change non-null values, and can be used to 
change a single value if needed. 
tcplConfSave modifies the TCPL.config file to reflect the current
tcpl settings.
tcplConfList lists the values assigned to the tcpl global options.
tcplConfLoad updates the tcpl settings to reflect the current 
configuration file.
tcplConfDefault changes the options to reflect the default
settings for the example SQLite database, but does not alter the 
configuration file.
tcplConfReset is used to generate the initial configuration script,
and can be used to reset or regenerate the configuration script by the user.
