Description

Since Qt 5.7, QtCharts (https://doc.qt.io/qt-5/qtcharts-index.html) is available in the OpenSource version of Qt.

I currently see three possibilities for MitkChart:

stick to C3js
use QtChart under the hood of MitkChart
remove MitkChart and use QtChart alone

We should do a well reflected decision (as we know now all requirements that we need) as soon as possible.

To bad :-( So I guess we'll stick to C3.js for now.
