## within current branch, squashes all commits that are ahead of master down into one
## useful if you merged with upstream in the middle of your commits (rebase could get very ugly if this is the case)
 
## commit any working changes on branch "mybranchname", then...
git checkout master
git checkout -b mybranchname_temp
git merge --squash mybranchname
git commit -am "Message describing all squashed commits"
git branch -m mybranchname mybranchname_unsquashed
git branch -m mybranchname

The crmID is predominantly used to fetch a person in `people_service` by looking by via the crmID.

compass.com/contacts/subscribers/newperson/handlers/process_invite.go:169 uses crmID to fetch a person. This call can be
avoided if `contactually.UserInvite` can return the users `external_id` from c10y.

src/go/compass.com/people/server/people.go:359 #GetPersonByCRMID method should be deprecated and a new a similar
method which queries based on personID should be used.
The existing `get /person` call could be used, but that endpoint seems to be doing a lot of other work.

Bulk of the usage of crmID happens in the `src/go/compass.com/people/api/agent.go` file which is used to create/update
