- interim release w11a_V0.562 (untagged)

- C++ and Tcl based backend server: many support classes for interfacing to 
  w11 system designs, and the associated Tcl bindings.
- add 'asm-11', a simple, Macro-11 syntax subset combatible, assembler. 
- use now doxygen 1.8.3.1, generate c++,tcl, and vhdl source docs
