* NOTE: The name= portion of a name=value pair may be converted to lowercase or
* uppercase when the object is initialized and when new data is added. This
* behaviour is determined by the url.case.folding property in
* TurbineResources.properties. Adding a name/value pair may overwrite existing
* name=value pairs if the names match:
*
* <pre>
* ParameterParser pp = data.getParameters();
* pp.add("ERROR", 1);
* pp.add("eRrOr", 2);
* int result = pp.getInt("ERROR");
* </pre>
*
* In the above example, result is 2.
