Compiling to Core v7

[Robert Scheller]

Dear All:

We are diligently converting all extension repositories over to Core v7.  In some cases, you requested that the conversion be placed into a branch, which I name 'Core_v7'.

The instructions to compile to Core v7 can be found here: https://docs.google.com/document/d/1sf_ENsdWkt_yHp-XmJwugAqq8ZmJE7bz3qsVom7hvsI/edit?usp=sharing

Please let me know if you have questions!
