Description

This issue grew out of TINKERPOP-2461 which noted issues with aligning imports to the GroovyTranslator. A more Groovy syntax for withStrategies() will help make script submission have a more unified, compact and consistent feel while not affecting the Java syntax which relies more on the type safe and IDE friendly builder pattern.
