[Ktechlab-devel] Multiple PIC clock speeds

[P Zoltan]

  I've comitted changes to the trunk that allow setting the clock frequency  
(steps per iteration) for gpsim processors. The current implementation  
allows setting different clock speeds to different PIC instances; however  
I consider the changes a but hacky. Please review it and maybe give some  
ideas.

  piccomponent
- added property "clock_mhz"
- in data changes, if gpsim processor not null, set step/iteration.
    It annoys me that the data changed is called even if the gpsim  
processor is null. Whould there be a warning?
- on creation of gpsim processor, set step/iteration

gpsim processor:
- private member added
- get/set method for it

  Maybe the new member should be set up in constructor...

simulator:
- iterate through the gpsim simulators and run each for the specified steps

  Please test it.
