/**
 * This class works as a dispatcher to run the correct main() function.
 * Note: FQLite does support 2 modes: command line interface (cli) and graphical (gui).
 * 
 * To run the FQLite from the command line you can use one of the  following options:
 *
 * $> java -jar  fqliteXXX.jar gui						: start program in gui mode
 * $> java -jar  fqliteXXX.jar nogui <database.db>       : starts the command line version
 * $> java -jar  fqliteXXX.jar cli <database.db>		    : starts the command line version
 * $> java -jar  fqliteXXX.jar                           : start program in gui mode
