[ANALYZER-2548] - Sunburst slice proportions are not equivalent to the represented values' proportions
* Renamed the AngleAxis to NormalizedAxis to be able to use it in the Sunburst and the Treemap.
[ANALYZER-2548] - Sunburst slice proportions are not equivalent to the represented values' proportions
* Cleanup the semantic mess of the use of the dimensions "#sum", and also whether the "abs" option should be used in each case or not.
** Created the Dimension#value and Dimension#valueAbs methods to abstract whether the aggregation is a sum or what not.
** The later always aggregate the datums' values directly: no abs!
** This is used in the cases where a Data, a group of Datums, is going to be plotted as a single visual element. The aggregation of the direct values is what matters.
** In other cases we wanted sums not related to this aggregation.
* Removed UseAbs option from the NormalizedAxis, cause it must always be true (it was only being used to control the datum aggregation, but that is now always without abs!).
[ANALYZER-2548] - Sunburst slice proportions are not equivalent to the represented values' proportions
* Actual implementation for Sunburst and Treemap, reusing the same axis, NormalizedAxis, that the PieChart uses for the angle-span scale.
* Removed the unnecessary setScaleRange; leaving the default scale ranges of [0, 1] holds the same results.
