     \brief Handles an incoming JSON-RPC request
     \param inputString received JSON-RPC request
     \param transport Transport protocol on which the request arrived
     \param client Client which sent the request
     \return JSON-RPC response to be sent back to the client

     Parses the received input string for the called method and provided
     parameters. If the request does not conform to the JSON-RPC 2.0
     specification an error is returned. Otherwise the parameters provided
     in the request are checked for validity and completeness. If the request
     is valid and the requested method exists it is called and executed.
