# The example below uses common command-line tools 
# `curl`, `jq` with the InfluxDB API to do the following:
# 1. Create a user.
# 2. Find the new or existing user by name.
# 3. If the user exists:
#   a. Build an authorization object with the user ID.
#   b. Create the new authorization.
#   c. Return the new token.
