/**
* Executes some presenting function on the server. The term "presenting" means
* a non writing (or modifying) idempotent request. There may be some
* side-effect allowed (like tracking calls to one presenter), but the main
* purpose is to get data of the server, which is not autoupdate-, projector-, or
* icc-data.
*
* Some purposes may be:
* - aggregating of login data
* - managing of whoami, if additional data is needed, that the auth service
* doesn't provide
* - To get history points
* - To get history data
* - To get the installed version
* - To query statistics
* - To calculate recursive trees (e.g. origins of motions; not possible with
* the autoupdate service)
* - to synchronize the servertime for countdowns
*
* @throws PresenterException This exception might be thrown, if there was an
* server error (Http-500-equivalent). For user error (e.g. wrong data) use the
* PresenterError interface
