openstudio_model.js port working

This took longer than I expected it to, partially because I wasn't expecting the .json input file, and partially because my javascript was a little rusty.

I tried to make a direct one-to-one port from `OpenstudioModel.rb` to `openstudio_model.js`. To accomplish this I modified the initial `buildingData.json` provided to have parameters that matched one for one what was used in the `x-retrofit-manager-MINIMUM.rb`.

I also added the `VirtualPULSE_default_constructions.osm` to the `jason` folder to make the example complete, to be able to test the execution.

Further, since it took longer than I expected, and `autosize.rb` does not contain any openstudio code at all, I left it un-ported.
