install a package directly from githuh, in this case we also specify a branch (note: this is useful for testing NPM packages without publishing them, but this will break on a Travis build if it is from a private repo.)
gulp watch
run the local build with live/hot reload
gulp build -q && gulp browser-sync
run the Isomorphic build in a closer to "prod" mode (ie no live/hot reload) without uglification and minification and start the BrowserSync server when finished
gulp build && gulp browser-sync
run the Isomorphic build and preview locally on BrowserSync
