  * @brief An enumerate for the different types of file notifications
  *
  * This enumerate provides a means to specify the type of events that you are interest in.
  * Valid values are:
  * <ul>
  *    <li>Access: The file was accessed (read)
  *    <li>Modify The file was modified (write,truncate)
  *    <li>Attrib = The file had its attributes changed (chmod,chown,chgrp)
  *    <li>CloseWrite = Writable file was closed
