/**
 *DAML_S_Profile_Client is a datatype that contains the structures into which 
 *a service description is loaded and the code that loads it from a URI.
 *The motivation for writing this class was to provide a very easy and 
 *convienient way to access the information required about a service description 
 *of the sort generated by Zeus for the purpose of using it in matchmaking and 
 *service composition, so the functionality is rather limited, but it should be 
 *easy to use.
