/**
 * Get a copy of the db collection class with
 *   Mongo/Amazon DocDB wrapper with functions that are
 *   equally compatible with both
 * @author Gabe Abrams
 * @param [opts] object containing all arguments
 * @param [opts.schemaVersion=1] the version of the schema. Whenever you
 *   change your schema, increment this number and dce-mango will automatically
 *   re-build and re-provision your collections
 * @param [dbName=env.DB_NAME ?? 'mango-store'] the name of the database
 *   to set up/use
 * @param [dbInfo=env vars] either include an object
 *   with a mongo-style url: { url } or include an object
 *   with pieces of a mongo-style url:
 *   { user, pass, host, [options] } where options
 *   is optional.
 *   Otherwise, dce-mango will use environment variables instead:
 *   either env.DB_URL or env.DB_USER + DB_PASS + DB_HOST must
 *   be included, optionally with an included DB_OPTIONS. You can also use
 *   mongo env vars: env.MONGO_URL or env.MONGO_USER + MONGO_PASS + MONGO_HOST
 *   and optionally MONGO_OPTIONS
 * @returns collection class that references the given database
