> 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.
