BCL 2.0 implementation ready for public testing

NREL has completed development of Building Component Library 2.0 and it is now available for public testing at https://bcl2.nrel.gov/. The main BCL website is deprecated and will be replaced replaced by this new implementation.

BCL 2.0 uses a set of GitHub repositories as the back-end for robustness, transparency, and flexibility: version-controlled Measures, Components, Weather Files, and more. Instructions are available on the new site for organizations and groups with BCL content to migrate their components and measures to GitHub repositories.
