Document how to test changes with OpenStudio #95
Description
As stated in #92 (comment), I'm unclear how I can test changes to this repo in OpenStudio / OpenStudioApplication.
Do I need to export a new OpenStudio-workflow-gem, then OpenStudio-gems, then rebuild OpenStudio? Is there an easier way (something like setting a GEM_PATH variable or whatever) that doesn't warrant building and uploading several packages before rebuilding from scratch?
