WIP Add possibility to select which array the Interpreter create

Nick Laurensonrequested to merge
LidarArraySelection into master

This MR try to solve #18, but does not work yet. T

he widget show up but don't list any array. image

In PV 5.4 (the current version used in LidarView) in addition to the vtkDataArraySelection, we must use the vtkSIArraySelectionProperty via the ArraySelectionInformationHelper. This force to implement some specific method.

In PV 5.6 this could be greatly simplify via the use of vtkSIDataArraySelectionProperty.

See this thread for more information
