Setup! +Index-time synonym expansion

[kenprice]

We need a way to set up a Solr test instance quickly and with a consistent state (same test documents ingested each time). In addition, the Solr instances we use must be configured to perform synonym expansion.

This PR should:

• Include a setup script for existing Solr core that has been configured with our schema that automatically ingests a set of documents. ("There's a script for that!" TM)
• Add more test documents (We could use more, however). These live in the setup directory along with the script.
• Provide new schema.xml and solrconfig.xml and include it in the repo. This is in the setup directory.
• New config files allow synonym expansion and index-time, and supports multi-term phrases. (#54)
• Have documentation for setup instructions.

Thanks @trojchanakasetchai for your help!
