/**
 * colorize
 * Description: Provides a function that may be used to style the output of a console application.
 *
 * Examples:
 *     colorize("Something bolded in cyan on red background", 'bold', 'on_red', 'cyan')
 *   You may use multiple styles together:
 *     colorize("Something bolded underlines and blinking.", 'bold', 'underline', 'blink')
 *
 * Text should always be the first argument, the last argument is a variable hash so you can have
 * as many arguments as you want:
 *
 *    print colorize("Something bolded", 'bold');
 *    print colorize("Something in cyan", 'cyan');
 *    print colorize("Something bolded in cyan", 'bold', 'cyan');
 *    print colorize("Something bolded in cyan on red" 
 *                          . "background while blinking and underlined", 
 *                          'bold', 'underline', 'on_red', 'cyan', 'blink');
