With this change any files that have been DELETED locally, but not
comitted as a change, will be removed from the sandbox when executing
the sandbox sync operation.
This change collects a list of what files have been deleted in the
repository and removes them from the sandbox via rm.
If those files have since returned (deleted but returned) they will
still be deleted but, since those files will be in your local copy will
be synced to the sandbox.
This change adds a 'sandbox.sh' script (and package.json scripts) that helps to move LOCAL changes to a sanxbox both for DEVELOPMENT or to DEPLOY CODE in preparation for production builds.
USAGE of the script is outlined in updates to README.md
Determines files to IGNORE by comparing what changed between the current
BRANCH divergence point and the TIP of TRUNK
Files can be WATCHED to trigger the rsync
