Description

Performance wise, it may be necessary for a filter to test a column for a specific value (like SingleColumnValueFilter) , but exclude the KeyValue from the output. This is certainly the case when the column values are large in size.

In order to keep SingleColumnValueFilter simple and maintainable, I decided to subclass it. SingleColumnValueExcludeFilter is the result. Tests are included.
