If you use browserify to concatenate your js files and to make them work as modules, the angular-validation js file is never picked up.

As a result, angular's DI err's with this message:

Failed to instantiate module ghiscoding.validation due to:
Error: [$injector:nomod] Module 'ghiscoding.validation' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

(this is because angular-validation.min.js is never added to the concatenated .js file)

The problem is in the package.json file in the angular-validation node_modules folder. "Main" should reference "dist/angular-validation.min.js", instead of app.js (I did find the app.js file concatenated in my output)
