/** An example that illustrates template matching on SIP headers and messages.
* This uses regular expressions for matching on portions of sip messages.
* This is useful for situations when say you want to match with certain
* response classes or request URIs or whatever.
* You construct a match template that can consist of portions that are exact
* matches and portions that use regular expressions for matching. 
* You might find this useful for bulding test frameworks.
