MuonLayerHough - Code cleaning

Hi everybody,

although the changeset here looks huge, the majority comes from a clang-format of the

• MuonSpectrometer/MuonReconstruction/MuonPatternFinders/MuonPatternFinderTools/MuonCombinePatternTools
• MuonSpectrometer/MuonReconstruction/MuonPatternFinders/MuonPatternFinderTools/MuonHoughPatternTools
• MuonSpectrometer/MuonReconstruction/MuonRecEvent/MuonHoughPatternEvent
• MuonSpectrometer/MuonReconstruction/MuonRecTools/MuonRecToolInterfaces
• MuonSpectrometer/MuonReconstruction/MuonRecUtils/MuonLayerHough

packages. All done in the first commit of this MR. The second commit contains the actual changes:

• Replace std::vector<double>(3) data types by Amg::Vector3D
• Augment the IMuonHoughPatternFinderTools with the set of functions to perform the pattern seeding using the NSW information
• This allows us to switch the tool in MuonHoughAlg to the interface class
• Pipe Amg::Vectors to the MuonHoughMathUtils functions where possible
• MuonHoughPatternFinderTool try to avoid the copy of information (hitx,hity,hitz) while the Hough patterns are built
• Employment of smart pointers
