Remove reference to nonexistent package HighPtBTrackingAnalysis.

Private data members should start with m_.

Allow overriding the location of test files via an optional environment
variable.  Useful for builds on systems where cvmfs is not available.

clang warnings: Missing override keywords.

Test has been timing out in nightlies.

Clang warnings: unused private data members.

Private data members should start with m_.

In C++11, implicit declarations of copy and assignment are deprecated if the
class has a user defined destructor or copy or assignment.  gcc9 now warns
about this by default.
Adjust to avoid the warning.

Also avoid potential memory problem copying TFileLooper objects.

Private data members should start with m_.

Lengthen timeout; ignore messages with filenames.
Allow overriding location of input file.
Fix unmerged component.

Add option to sg-dump to skip events before starting dumping.

Make const a number of methods that can trivally be so changed.

Remove m_pRwChVec, m_cell2Double.
Create these objects on the stack where needed.
Change from a vector of pointers to a flat vector to remove most of the
allocation/deallocation overhead (which is probably why they were members
in the first place).

Clang warnings: unused private data members.
