Closes #30.

Closes #33.

The `kuromoji` analyzer is not registered as a global analyzer, so this fails:

    POST /_analyze?analyzer=kuromoji&text=J R 新宿駅の近くにビールを飲みに行こうか

    {
       "error": "ElasticsearchIllegalArgumentException[failed to find analyzer [kuromoji]]",
       "status": 400
    }

But this succeeds:

    PUT /t
    POST /t/_analyze?analyzer=kuromoji&text=J R 新宿駅の近くにビールを飲みに行こうか
