[Paraview] pqViewManager in Clone2

[Alexis Chan]

Hi

Here's the file:
https://github.com/alexisylchan/ParaView/blob/testTwoViews/Plugins/VRPN/pqVRPNStarter.cxx

I commented out the last view creation. Now ParaView can load the plugin and
create a second window but it's not a functional view. (See
screenshot<http://cs.unc.edu/%7Ealexisc/ParaView/twowindows.png>
)

Thanks!!
