Caution please. Do not update nor use this relase until green light comes. For details please see doc/release.notes.

 - use DetectorSelector in dumpdetector

 - changed method signature: LCDD::detectors(unsigned int includeFlag,  unsigned int excludeFlag=0 )
   - allows to select sets of detectors with some properties and explicitely excluding others
   - see dumpdetector for example usage

  - added LCDDImp::detectors(unsigned int typeFlag, bool bitsSet)
  -> allows to set detector properties (with DetType) for DetElements and
    get sets of detectors with certain properties, e.g.
    ( DetType::TRACKER | DetType::BARREL ) selects all barrel trackers

   a flag wordL DetType
 - added test_DetType.cc

 - removed random lines drawn in teveDisplay
 - dont't print DetectorData by default in dumpdetector

 - used in dumpdetector:
   dumpdetector compact.xml -d 

Rename target to DDRec, this required changes in many other CMakeLists to be consistent

Re-arrange Gear dependent parts into single if scope
Add SYSTEM to GEAR IncludeDirs

Use variables to define libraries in one place and add optional ones (i.e., gear) to the list

Create plugin_sources variable to create a DDRecPlugin independent of the DDRec library parts

No Whitespace after and before parenthesis
Assume ROOT_INCLUDE_DIRS is added in main CMakeLists file
Comment Setting of CMAKE_CXX_FLAGS

    - in a next step the SurfaceManager will
      be re-written to be a singleton that
      caches surface lists and maps ...

 Update teveDisplay for better visualization resolution on Tube. For example TPC, Hcal outer shape and Coil.

   to be used to only build detector envelopes
 - fixed visualization in teve_display to also
   show the envelope volume
 - visualize daughter level in dumpdetector (tabs)

   shows all DetElements in model incl. #surfaces
