* Removed workaround code (now normalized values: [0,1])
* Pending: marker sync issue (see previous commit)

* Marker was invisible due to erratic pulse profile values (remove workaround when fixed!)
* Improved updates of profile and marker items

* Fixed item handling (store them on heap)
* Removed scope axes
* Vertical size now determined by marker/pulse (normalized to 1)
* Removed dummy data
* FIXME: marker not visible despite higher z-layer

* Looks much nicer in conjunction with 3D part
* Matches cones

* Basic curve rendring (still using mock data vector)
* Basic axes: no ticks, no labels -> no Qwt ;-)
* Marker showing current pulse phase (normalized to one pulsar spin period)
* Communication with OpenGL widget
