ResponseBuilder public flags

[Tricia Williams]

Hi,

   I'm working on a custom SearchComponent to display context stored in 
payloads.  I noticed that both the FacetComponent and the 
HighlightComponent are tightly coupled with the ResponseBuilder through 
the frequent use of doFacet and doHighlight.  If I am building a 
component with similar functionality to highlighting/faceting that will 
need to check a similar flag how can I do this as a plugin (ie without 
making any modification to the ResponseBuilder)?

   How are people feeling about the stability of this API?  Is this the 
right way to approach this?

Thanks,
Tricia
