Method createTempFolder

app/src/processing/app/Util.java:216–228

Create a temporary folder by using the createTempFile() mechanism, deleting the file it creates, and making a folder using the location that was provided. Unlike createTempFile(), there is no minimum size for prefix. If prefix is less than 3 characters, the remaining characters will be filled with

(String prefix, String suffix,
                                      File directory)

   * filled with underscores
