//To build dist/thrift.js, dist/thrift.min.js and doc/*
//run grunt at the command line in this directory.
//Prerequisites:
// Node Setup -   nodejs.org
// Grunt Setup -  npm install  //reads the ./package.json and installs project dependencies
// Run grunt -    npx grunt  // uses project-local installed version of grunt (from package.json)
