Detailed Description

Report filter.

Represents abstract filter of reported messages with location. Each inherited filter is intended to either perform an optional transformation on a report and call process_output(), or filter it out by not calling process_output(). Individual filters' create methods should reserve first parameter to specifying output, followed by other specific parameters, to enable easy chaining of filters.
