Removes ignored or private fields from a resume object

scrubbed: the processed resume object
ignoreList: an array of ignored nodes that were removed
privateList: an array of private nodes that were removed
}

# [^1]: As of v0.6.6, the NPM traverse library has a quirk when attempting
# to remove array elements directly using traverse's `this.remove`. See:
#
# https://github.com/substack/js-traverse/issues/48
#
# [^2]: The workaround is to use traverse's 'this.delete' to nullify the value
# first, followed by removal with something like _.compact.
