• change the imports to the new package for ST
• change the members of a rules return scope to use ST not StringTemplate. Also change toString() method to call render.
• we need a blank library of templates to avoid a null pointer if someone forgets to set the library. change:

  Code Block
  protected StringTemplateGroup templateLib = new StringTemplateGroup("<name>Templates", AngleBracketTemplateLexer.class);

  to

  Code Block
  protected STGroup templateLib = new STGroup();

• get rid of the definition of STAttrMap altogether; we don't need it anymore because ST.add() it allows us to chain calls to add multiple attributes as part of a single expression.
• the previous item lets us convert:

  Code Block
  rewriteExternalTemplate(name,args) ::= << templateLib.getInstanceOf("<name>"<if(args)>, new STAttrMap()<args:{a | .put("<a.name>", <a.value>)}> <endif>) >>

  to

  Code Block
  rewriteExternalTemplate(name,args) ::= << templateLib.getInstanceOf("<name>") <if(args)><args:{a | .add("<a.name>", <a.value>)}><endif> >>

  There are three methods like that.

If you look at an ST.stg difference, there's not much to do.
