Extracting a string or token from its input argument

The ParseResponse class extracts a string from its input argument. The ExtractToken class extracts a particular token (string) from its input argument. Both classes can be useful for handling certain types of dynamic data correlation.
The ParseResponse class extracts a string from its input argument, using a regular expression for pattern matching.

/** 
 * The ParseResponse class demonstrates using Custom Code to extract a 
 * string from its input argument using a regular expression for pattern 
 * matching. 
 * 
 * In this sample, the args[0] input string is assumed to be the full 
response  from a previous request.  This response contains the day's 
headlines in a format such as: 
 * 
 *   <a class=f href=r/d2>In the News</a><small class=m>&nbsp;<span id=nw> 
 *   </span></small></h2> 
 *   <div class=ct> 
 *   &#149;&nbsp;<a href=s/213231>Cooler weather moving into eastern 
U.S.</a>  *   <br>&#149;&nbsp;<a href=s/262502>Digital camera shipments 
up</a><br>  * 
 * Given the above response, the extracted string would be: 
 *        Cooler weather moving into eastern U.S.

 *         '30181','Rational','1','null','1','1','6fd8e261','RPT')
