Add Polar chart support...
Add Polar chart support This commit also heavily refactors things as polar chart needs separate implementation of various classes that previously only needed one, such as ChartAxis and ChartLayout.

\example examples/linechart
\title LineChart Example
\subtitle
The example shows how to create simple line chart.
\image examples_linechart.png
To create line chart, QLineSeries instance is needed. Let's create one.
\snippet ../examples/linechart/main.cpp 1
Then we add data to series. We can use append() member function or use stream operator.
\snippet ../examples/linechart/main.cpp 2
To present the data on the chart we need QChart instance. We add the series to it, create the default axes and set the title of the chart.
\snippet ../examples/linechart/main.cpp 3
Then we create a QChartView object with QChart as a parameter. This way we don't need to create QGraphicsView scene ourselves. We also set the Antialiasing on to have the rendered lines look nicer.
\snippet ../examples/linechart/main.cpp 4
Chart is ready to be shown.
\snippet ../examples/linechart/main.cpp 5
