 * The following is a sample gulp file for getting the list selection size from the command prompt
 * Note: Gulp Prompt is a wrapper around inquirer.js so if it is available in inquirer.js 
 * it should be available within gulp-prompt.  The prompt function is essentially a straight
 * passthrough to the inquirer.js library.  The page size variable is what sets the length of display
 * items in list
