   o RooExtendedTerm

     - New p.d.f. class that has no shape but just introduces
       an extended likelihood term


   o RooCmdConfig

     - Add production to null pointer in decodeStringOnTheFly()


   o RooAbsReal

     - Fix attachment to of TTree branches that are not of type Double_t.
       

   o RooAddPdf 

     - Remove forgotten debug print statements


   o RooObjCacheManager

     - In optimizeCacheMode() remove old snapshot of cacheObservables
       only after new snapshot has been created to resolve cyclical
       dependency problems where new snapshot is modeled on old snapshot.

   o RooAbsPdf

     - Add redirectServersHook() that clears _norm pointer

     - Add checkfor null _norm object in getVal() and retrieve
       new normalization object in such cases from syncNormalization()

     - Migrate messages in generate() to RooMsgService
  

   o RooMultiCatIter

     - Remove requirement that input categories are lvalues as this
       is not required.


   o RooSimPdfBuilder

     - Add check in build code that verifies that auxiliary splitting categories
       used in composite splits do not depend on any other category of that
       composite split, i.e. you cannot split in f(x),x, only in f(y),x


   o RooMinuit

     - Add protection in contour function agains Minuit failures which cause
       a null TGraph pointer to be returned


   o LinkDef3.h,Module.mk

     - Add class RooExtendedTerm

  Summary (see branch logs for more details):

  - Set of changes related to CPU quota control including
    - broadcast of centrally determined priorities
    - mechanism to renice processes in a quantitative way
  - New packetizer for non-tree based analysis and related API in TProof (from L. Tran-Thanh)
  - Support for merging output objects saved in files on the workers (from L. Tran-Thanh and me)
  - Improve version binary compatibility checks using also the SVN revision number
   (when available) to define the running version.
  - Extend the version binary compatibility checks also to the cached selector binaries.
  - Extend TDSet::Lookup so that in case of missing files, it can remove them from the
    dataset (option removeMissing must be set).
  - Move the data set lookup to the TProofPlayerRemote::Process.
  - Handle properly the case of incomple datasets: if the file is not found in the lookup
    don't try to validate it; add it, instead, to a 'missingFiles' list returned in the
    output list (fixing bug #28800 in Savannah).

	relative to fCamBase.

        Implement a common Truck(), Rotate() and Dolly() function for
	orthographic and perspective camera.

	Implement an option to define camera center point
	externally. Center can also be determined via picking.
