> This filter is modeled off of the RegExFilter class in the org.apache.accumulo.core.iterators.user package. It allows you to specify a lexicographical start and end (including whether or not it is inclusive on each side) to a range of column qualifier keys that you would like returned from the retrieved data set on a Scanner or BatchScanner. It sets options on its IteratorSetting with a static method (setSlice), and is added to a Scanner/BatchScanner using addScanIterator like normal iterators/filters. This filter is intended to be an Accumulo equivalent to HBase's ColumnRangeFilter.
