 * Purpose: join strings into one, placing separator in between them,         *

 *          skipping empty strings                                            *

 * Parameters: separator - separator to place in between strings              *

 *             count     - number of strings                                  *

 *             ...       - strings to join (strings can be empty  or NULL)    *

 *                                                                            *
