DB_QueryTool Description
 This package is an OO-abstraction to the SQL-Query language, it provides methods such
 as setWhere, setOrder, setGroup, setJoin, etc. to easily build queries.
 It also provides an easy to learn interface that interacts nicely with HTML-forms using
 arrays that contain the column data, that shall be updated/added in a DB.
 This package bases on an SQL-Builder which lets you easily build
 SQL-Statements and execute them.
      
        You can find some useful usage examples and docs in the
        
        MDB_QueryTool documentation.
        Everything there holds true for DB_QueryTool too,
        except for the class name, of course.
