This is my attempt to build from scratch a version of angular
Actually it is based on book "Tero Parviainen - Build Your Own Angularjs"
#Issue with testem atal error: spawn phantomjs ENOENT
teropa/build-your-own-angularjs#88
in file: node_modules\grunt-contrib-testem\node_modules\testem\lib\browser_launcher.js
it was the line line 120 (not 123 as mentioned above) exe: 'phantomjs', ---> exe: 'phantomjs.cmd',
