gradle for backend module

// Currently, the appengine gradle plugin's appengine devappserver launch doesn't interact well with Intellij/AndroidStudio's
// Gradle integration.  As a temporary solution, please launch from the command line.
// ./gradlew modulename:appengineRun
// If you would like more information on the gradle-appengine-plugin please refer to the github page
// https://github.com/GoogleCloudPlatform/gradle-appengine-plugin
