ScriptEngine with fresh imports.  Waits for any existing script evaluations to complete but
 then blocks other operations until complete.public void addImports(Set<String> imports)

 DependencyManager interface.  Waits for any existing script evaluations to complete but
 then blocks other operations until complete.public List<GremlinPlugin> use(String group, String artifact, String version)
ScriptEngine and determine if it
 implements DependencyManager.  For those that do call the @{link DependencyManager#use} method to fire
 it up.  Waits for any existing script evaluations to complete but then blocks other operations until complete.public void loadPlugins(List<GremlinPlugin> plugins)

ScriptEngine implementations and if they implement AutoCloseable
 then call the AutoCloseable.close() method. After that is complete, the script engine cache will be
 cleared.close in interface AutoCloseableExceptionpublic void reset()
