title: gulp.src() include files but ignore all folders
body: <p>There is certainly such a simple answer to this that I can't find anyone that's asked it before:</p>
  
  <p>What globbing pattern to include all the files in a folder but ignore ALL subfolders?</p>
  
  <p>gulp.src('*') includes all files and folders. I just want the files and would rather not have to exclude the folders individually.</p>
