/**
* Builds SqlMapClient instances from a supplied resource (e.g. XML configuration file)
* <p/>
* The SqlMapClientBuilder class is responsible for parsing configuration documents
* and building the SqlMapClient instance. Its current implementation works with
* XML configuration files (e.g. sql-map-config.xml).
* <p/>
* Example:
* <pre>
* Reader reader = Resources.getResourceAsReader("properties/sql-map-config.xml");
* SqlMapClient client = SqlMapClientBuilder.buildSqlMapClient (reader);
* </pre>
* <p/>
* Examples of the XML document structure used by SqlMapClientBuilder can
* be found at the links below.
* <p/>
* Note: They might look big, but they're mostly comments!
* <ul>
* <li> <a href="sql-map-config.txt">The SQL Map Config File</a>
* <li> <a href="sql-map.txt">An SQL Map File</a>
