I made a number of changes to Trick to make it compile clean with
clang++ -Wdocumentation, which checks doxygen comments. The changes
were either to comments or to parameter names in function declarations.
None of the changes have any impact on the compiled code.
Taking in the latest er7_utils directory and adding it into Trick in the
same location it was as an external repository. Made one change to
the files_to_ICG.hh file in the repository to remove the CheckpointHelper
header files. Those go in the Trick files_to_ICG.hh file.
