The deployment script can be ran also on testrpc/ganache:

-clone smart-contracts repository.
-run "npm install"
-run "testrpc" in another terminal/tab.
-run he deployment script: "./node_modules/.bin/truffle test scripts/deployment.js"

notes:
-The script uses test tokens, which it generates according to the json file at smart-contracts/deployment_input.json.
-At the test part under "set eth to dgd rate" we init rates for 1 token. In order to change/add tokens this part should be modified.
