Enter QA environment with basic search/browse functionality

Configure Solr
Add IndexService library
Index and delete sample data with rake task
Generate catalog controller to customize blacklight
Show search results in catalog home view
Basic keyword search
Refine search with facets
Show basic metadata for single record

To test in your browser:  Follow the new README instructions to configure and start the dummy application, and index sample data to Solr.  You may need to visit [http://127.0.0.1:8983/solr/#/~cores/blacklight-core](http://127.0.0.1:8983/solr/#/~cores/blacklight-core) and click `Reload` for the sample data to index. Go to [http://localhost:3000/catalog](http://localhost:3000/catalog) (you will see the same page if you go to http://localhost:3000 because of the current route configuration).  You should see your sample record.  You should be able to search and refine your search with facets.  You should also be able to view some basic metadata for a single record if you click on the record id.  

There are also two unit test you can run with `bundle exec rake ci`.

Because we are likely moving away from Solr, I focused on getting Solr working without necessarily employing the most elegant solutions.  

In `schema.xml`, everything above line 476 `<fields>` is standard.  Everything below is ours, with the exception of `dynamic field definitions`, which is also standard.
You should be able to use the factory the same way you would in the test environment.

You may need to load up some of the things that `spec_helper` would take care of for you.  In your (e.g. rake task) do:

```ruby 
require 'factory_girl'
include FactoryGirl::Syntax::Methods
require 'dpla/map/factories'
```

Then you should be able to do `my_agg = build(:aggregation)`, or whatever else you need.
