Feb.26 Composite FBs with just FBDK FBs Tricks

Blinker with Flip-flop logic in a composite FB type in group util and named flipflop.

Tricks needed:

In 4DIAC 

1. create the composite FB as desired

2. use the composite FB from the palette in an application
3. map application to FBDK device via System

Before testing:

In 4DIAC preferences for FBDK

• add the group util to the list of packages 

In FBDK editor 

• open the xml for the composite function block
• Fix what ever it complains about. In this case:
• removed standard in
• removed xml statement with no explicit beginning xml statement
• add imports needed (import fb.rt.hmi.*;) 
• to Compiler Info / Header
• press Enter (lose what typed if forget)
• press OK button

• then save as and check XML and Java then the press the OK button 

Ready to test in 4DIAC deployment  using launch FBDK / (check appl) download.

Note: Received updated 4DIAC from Monika, because can't delete FB in composite FBs  in    last pre-edition.

Failed attempt:  Composite blocks had a problem with spliting and merging events using connectors so tried with E_SPLITs and E_MERGEs. The updated 4DIAC from Monika fixed this problem, too.
