In sqlalchemy, there are some advanced filter criterion but such filter criterion is not supported in OVO. An example is the "not in" criterion which is achieved by "query.filter(~db_model.column.in_(values))". Another example is the "not equal" criterion which is achieved by "query.filter(db_model.column != value)" This commit adds support for custom filtering. We introduce a base class called "FilterObj" from which the custom filter class should inherit. This commit also implements two filter class: one for implementing the "not in" criterion and the other for the "not equal" criterion. In addition, it makes StringMatchingFilterObj inherit from the FilterObj class.
