origin
This collects all of the subsetters that make decisions on the contents of an event.
Example
<removeEventDuplicate/>
This consists of
<removeEventDuplicate>
<eventAttrName>
<geographicalRegion>
<seismicRegion>
<originTimeRange>
<magnitudeRange>
<originDepthRange>
<originPointDistance>
<originPointAzimuth>
<originPointBackAzimuth>
<pointLinearDistanceMagnitude>
<eventArea>
<eventBoxArea>
<eventPolygonFile>
<catalog>
<contributor>
<originArrayAND>
<originArrayOR>
<originAND>
<originOR>
<originNOT>
<externalOriginSubsetter>
<youngerThan>
<printlineEventProcess>
