  Select the correct database library file:
  the library file must define the following functions:

  getDBVersion() - returns the name and version of the database software
  
  getDBtables($db) - returns array of table names for the specified database
  
  doQuery($query,$label) - run the query, and return the result:
        (boolean FALSE) : indicates the query failed
        (integer 0)     : query affected no rows, and returned no rows - e.g. an empty(SELECT)
        (integer >0)    : the number of rows affected by an INSERT, UPDATE or DELETE
        (array)         : SELECT was successful, and has returned a number-indexed array of records,
                           each record is an associative array of field names=>field values.

  safeIntoDB($value,$key) - to make a value safe for database processing,
                            by escaping any control characters

  getsql($querylabel,$values,$sort) - to return the sql query text,
                                              for query with name: $querylabel

  sqlparts($part,$values) - to return the sql query subclause text,
                                        for the subclause with name: $querylabel

  connectdb($config) - to open a connection to the database, and return the connector handle
