/**
* Use this file to configure your truffle project. It's seeded with some
* common settings for different networks and features like migrations,
* compilation and testing. Uncomment the ones you need or modify
* them to suit your project as necessary.
*
* More information about configuration can be found at:
*
* truffleframework.com/docs/advanced/configuration
*
* To deploy via Infura you'll need a wallet provider (like truffle-hdwallet-provider)
* to sign your transactions before they're sent to a remote public node. Infura API
* keys are available for free at: infura.io/register
*
* You'll also need a mnemonic - the twelve word phrase the wallet uses to generate
* public/private key pairs. If you're publishing your code to GitHub make sure you load this
* phrase from a file you've .gitignored so it doesn't accidentally become public.
