+ * A singleton class to access the default SqlMapper.
+ *
+ * Usage: Call configure() once, then use instance() to obtain a TSqlMapper
+ * instance. 
+ * <code>  
+ * TMapper::configure($configFile); 
+ * $object = TMapper::instance()->queryForObject('statementName');
+ * </code>
+ * 
+ * If your configuration file is named 'sqlmap.config' you may skip the
+ * configure() call.
