Steps to run server
-------------------

 - Install NodeJS and NPM

 - In 'lib' dir, run:
      cd lib
      npm i serve-handler ws uuid

 - Setup server state directory.
      mkdir /desired/path
      mkdir /desired/path/ops
      mkdir /desired/path/branches

 - In root dir, run:
      DRAWIOSTATEDIR=/desired/path node lib/versioning/run_server.js

   The server will also act as a static file server, hosting the drawio web app. Default port is 8700.


Steps to build + run client
---------------------------

 - Build SCCD model:
      cd lib/versioning
      python -m sccd.compiler.sccdc -l javascript -p eventloop client.xml -o client.js

 - Browserify plugin:
      cd src/main/webapp/plugins/cdf
      browserify versioning.js > versioning.browser.js

 - Make sure server is running and navigate to
      http://localhost:8700/src/main/webapp?dev=1&p=versioning
