Waiana service module

Waiana service module implements a local topic map storage used with an API compatible with the Maiana API. Maiana and Maiana API build up a topic map storage created and hosted but the Topic Maps Labs. As the Topic Maps Labs is not really working anymore, the status of Maiana and it's API are more or less vague. The Maiana has been broken for several years. Wandora originally supported Maiana API and allowed import and export of topic maps between Maiana and Wandora. The Waiana service module has been implemented to infuse new life into the import and export features, already implemented. Although the Waiana doesn't support topic map browsing but an storage API only, it is probably useful if the user wants to set a shared topic map storage.
