Detailed Description

This class allows the creation and update of
a pick context for one view of the viewer.
A context allows the control of different parameters
before the activation of a pick.

• the pick aperture.
  
• the depth of pick, the number of sub-structures selected.
  
• the order of picking, the possibility to traverse
  the pick structures starting from the root
  or the leaves.
