        ==Background==
        
        DSE is concept of caching SQL-statements, both inserts and updates, and executing them when a specified
        number of statements has been prepared. This is done using DB API cursor.executemany(list of cached statements)
        and this is way faster than executing SQL-statements in sequence.
        
        DSE also is a way to solve a recurring problem when using the Django ORM; how to insert or update a bunch of
        records without the huge performance hit of using the ORM to do it, for instance when you want to
        scan a filesystem and add or update a record for each file found.
        
        It has been designed to be used outside Django as well, but the main focus is good Django integration.
        
        ==Release notes==
        
        0.8.2 : - added 'pysqlite2' to _DBMAP. Thanks to David Marble for 0.8.1 and 0.8.2.
        
        0.8.1 : - attempt to fix quoting problems with fields on postgresql.
        
        0.8.0 : - fixed crash when more than one database connection has been configured. No ModelFactory will be triggered.
        
        0.7.0 : - don`t remember.
        
        0.6.0 : - added support for the with-statement.
                - added an ModelDelayedExecutor-instance to each model, so you can do Model.dse.add_item
                  instead of dse.ModelFactory.Model.add_item.
                - renamed dse.modelfactory to dse.ModelFactory to be more style-compliant.
        
        0.5.1 : just some notes on transaction handling.
        
        0.5.0 :
            - added modelfactory. Upon first import a modelfactory will be created in the DSE module. It`s basically just a
            helper-class containing ModelDelayedExecutor-instances for all models in all apps found in INSTALLED_APPS in
            settings.py.
            - to change the default item limit before automatic execution of cached SQL statements to 10000 instead of the default 1000::
        
            import dse
            dse.ITEM_LIMIT = 10000
        
        0.4.0 :
            - fixed serious bug when using mass updates. Using cursor.executemany is only possible when values
            for all columns are specified. If only values for a subset of the columns is specified that will be
            executed as a seperate SQL-call. NOTE! Using dex.get_items() or Djangos Model.objects.values() will give you
            all the fields.
            - code clean-up.
            - added custom exceptions; UpdateManyException, UpdateOneException and InsertManyException.
