 // This class' most important responsibility is to manage the ContributionsMap.
 // This class serves as a container for those objects.  Although it would have
 // been acceptable to let this class be a dumb container object, it turns out
 // that there was no other convenient place to put the Init() and
 // PostAndProcessCommitResponse() functions.  So they ended up here.
