Import warnings during multiprocessing

[Condor323]

During multiprocessing via the vensim wrapper I recieve the following 2 warnings for each active core. As you can imagine this clutters the output window during setup when running many cores. The problem is that there is no build in function to turn the warnings off or that these warnings are generated in this setup.

ImportWarning: netlogo connector not available
  from ema_workbench.connectors.vensim import VensimModel
ImportWarning: simio connector not available
  from ema_workbench.connectors.vensim import VensimModel

I agree this needs to be handled more elegantly. In the meantime, you can work around this via warnings.simplefilter.
