/**
 * This script prepares a release package to be pushed to npm

 * It will:
 *    * It updates the version in json/gradle files and makes sure they are consistent between each other (set-rn-version)
 *    * Updates podfile for RNTester
 *    * Commits changes and tags with the next version based off of last version tag.
 *      This in turn will trigger another CircleCI job to publish to npm
