Hub modal and initial angular Routes complete

 - Completes a full working Add Hub functionality.  Test it by going to
```
http://localhost:3000/#/newgroup
```
  or by using the lookup "add one".

 - Adds several Angular routes. Some to try:
```
http://localhost:3000/#/angular
http://localhost:3000/#/hungry
http://localhost:3000/#/anythingyouwant
```

 - This PR does disable the ability to save a vote, simple because the new Angular routes are disabling Rail's ability to save. My preference is to let that be the case and get busy converting all routes to Angular / json saving.

 - This PR is inclusive of all Angular work to-date and so replaces the "Angular Routing Working" PR

*** Please test and merge this PR ASAP so we can use it as a base to move forward.
