// config
//
// A configuration map, read from a config file (league.dat)
//
// Implemented as a Singleton. I.e. only instance exists
// at any given time, and should be accessed via the
// the_config() function. For this purporse, all config's
// constructing options are private and the_config is a
// friend returning a reference to a static config object
//
// load_config_file - loads a configuration map from a
//                    given file
//
// get_config_value - returns a value associated with a key,
//                    or "" if the key doesn't exist
//
// get_int_config - returns an integer value associated with
//                  a key (must have numeric value), or a
//                  default if the key doesn't exist
