/** \brief Panel widget using tulip data to compute statistical results.
*
* This class is a widget which takes places in the main interface of tulip, in the tabwidget of properties.
* This panel has mainly 3 uses :
*
* -Firstly : It changes the graph placement and order it under the form of an histogram or a scatter plot according to a defined number of metrics (up to 3).
* -Secondly : It computes and display some basic statistics results on the graph : average, variance, standard deviation, bounding box, linear regression and eigenvectors.
* -Thirdly : It clusterize the graph by a plane which is based upon statistic results calculated above.
