> A filter which takes as input a prefix and selects keys with columns containing that
prefix. Should be able to support advanced seeking. That is if, the scanner is at beginning
of the file, it should directly go to the point where the set of columns may start. Similarly,
it should exit out of a row as soon as it is done with the required set of columns.
