Necessary Maintenance #1026
Duplicated code for branch name element verification
The rules for verifying "instance names" and "friendly class names" appear in both ProductRegistryHelper and BranchDescription. They should appear in only one place, probably BranchDescription, so that we don't end up with inconsistent rules.
At the same time, the file FriendlyName.cc can probably be done away with, and the relevant behavior added to BranchDescription, which is almost the only place it is used.
