**Current behavior**
I need to add ability to handle cookies, tried to add https://github.com/salemdar/angular2-cookie; it has directions for using with this seed.

when i try to install i receive the error. 
+-- UNMET PEER DEPENDENCY @angular/compiler@2.1.
+-- UNMET PEER DEPENDENCY @angular/core@2.1.2

I suspect this has something to do with "@angular/compiler-cli": "~2.1.2" but unsure how to resolve. 

**Expected behavior**
npm install -s angular2-cookie correctly installs

**Minimal reproduction of the problem with instructions**
npm install -s angular2-cookie
observe unmet peer dependency

**What is the motivation / use case for changing the behavior?**
dealing with an ancient authentication system that needs cookies passed.
