Avoid calling functions that may return null via a reference.

Allow testing whether a CylinderSurface has a bounds object (it can be missing
depending on how the object was constructed).  Allows avoiding undefined
behavior sanitizer warnings from event dumping.

	* Added AnnulusBounds to the TrkSurfacesDict.h
	* Tagging as TrkSurfaces-01-03-31

2016-05-11 Attila Krasznahorkay <Attila.Krasznahorkay@cern.ch>
	* Removed the executable flag from all of the source files of the
	  package.
	* Replaced the usage of DataModel with AthContainers, and CLIDSvc
	  with SGTools in the code and the build configuration. (For both
	  CMT and CMake.) As the latter are the packages to use since a
	  while.
	* Fixed the CMake configuration not to try to link against the
	  non-existent TrkParametersBase library.
	* Did some general cleanup in the CMakeLists.txt file, removing
	  everything from it that's not needed.
	* Tagging as TrkSurfaces-01-03-30

2016-04-28 Sabine Elles
	* Add CMakeLists.txt in the most recent tag
