Example class implementing IUnitRequest to query a set of distributed BioCASE providers on the world wide web. The code shows how to create a scan request and its xml representation. The contProcessing method (required when implementing the IUnitRequest interface) does two things in this example:

a) logging a message for PosterThreads not returning a reponse document in time.
b) sending the list of responses as an email.
