------------------------------------------------------------

Will add:

RouteText.Route - The name of the relationship to which the FlowFile was routed.
RouteText.Group - The value captured by all capturing groups in the 'Grouping 
Regular Expression' property. If this property is not set or contains no 
capturing groups, this attribute will not be added.

Edits are also needed for the "Grouping Regular Expression" property 
description:

If multiple Capturing Groups exist in the Regular Expression, the -Group- 
*values* from all Capturing Groups *will be concatenated together*. Two lines 
will not be placed into the same FlowFile unless -the- they both have the same 
value for the Group (or neither line matches the Regular Expression).

> RouteText will write the relationship to which a flowfile is directed 
> (RouteText.Route) and, if it was resulting from a matching captured group, 
> would include the RouteText.Group attribute.  This is currently not captured 
> in the generated docs for the processor.
