/**
* The instance check around the class - if (!class_exists... -
* makes sure that we get called here once and once only in any instance
* of php - i.e. by the first non-SCA client to include SCA, or the target
* component in a web request.
*
* There are three different ways we can find ourselves here.
* 1. We have been included by a non-SCA client script. It is presumably
* later going to call getService() and/or createDataObject().
* 2. We are the target of an HTTP request for WSDL, SMD, etc. i.e. a service file
* 3. We are the target of a web request of some sort: WS, JSON, etc.
*
* How do we distinguish these to do the right thing?
* 1. Generate a class name from the name of the including file and see
* if it exists. If not, then we are in a plain old client script.
* If the class does exist but doesn't have @service then it is still
* just a plain old client script.
* 2. This is a request for a service file if we are the target of an
* HTTP request and we have the expected ?wsdl, ?smd etc. on the URL
* 3. Consider this is a web request otherwise, since we have been included
*
* We would get caught out if a non-SCA script were simply to
* to include a component rather than including SCA and using getService
* to get a proxy to it.
