Fixes for MooSegmentCombinationFinder
Trying to get MooSegmentCombinationFinder working in MT
- Moved to Gaudi's new property declaration and added missing property for m_segmentSelector
- Add ATLAS_CHECK_THREAD_SAFETY to MuonEDM_AssociationObjects, MuonRecHelperTools, MooSegmentCombinationFinder.
There is one big issue remaining - IMuonHoughPatternFinderTool is still public, because I think that at runtime this is set to MuonLayerHoughTool, which is a shared public tool (and which needs some serious work).
