In order to build and run the library LOCALLY, run

1. yarn install or npm install depending on your preference
2. make sure you have testrpc running , and change truffle.js to point to that network. e.g. localhost:8545.
3. truffle compile to create the json contract artifacts
4. truffle migrate to deploy the contracts onto the network
5. truffle test to test the contracts on the network

Linting your app is easy -- just run npm run -s lint!
