The tool was caching event information in member variables.
Rework to remove some of this information and assocciate the rest
with the TrackSurfaceIntersection object.
Results are identical, as per RunTier0Tests.

Also changed CRLF line endings to LF.

clang warning: unused private data member.

AthenaAttributeList was allowing an implicit conversion from coral::AttributreList.
This was seen to be causing copies to be made of an AttributeList where this
was not intended.  Make the AthenaAttributeList conversion constructor explicit.

Give PackedArray a default constructor so that it will work
with CachedValue.
