Parse and validate parameters specified in Information Console URI directives.

Create XML API structures based on Actuate Information Console requests.

Submit XML streams to the Actuate SOAP API.

Handle responses from the Actuate SOAP API, including detecting errors.
Store constant session information, such as the name space and SOAP endpoint.
