/**
 * This action allows the user to clip several kinds of MeshComponents : vtkStructuredGridClip,  vtkUnstructuredGridClip, vtkPolyData.
 *
 * This action allows 2 clipping modes :
 * - Only selected meshes are clipped
 * - All the opened meshes are clipped
 * The switch between those 2 approaches can easily be processed thanks to the related button in the action viewer.
 *
 * This action uses a vtkImplicitPlaneWidget which can be either hidden or visible thanks to the related button in the action viewer.
 *
 * This action can also restore the clipped meshes to their former "unclipped" state thanks to the restore Meshes button.
 * Basically, when you're done using the clipping tool, you can, for example, restore the initial unclipped meshes and hide the plane
 * before switching to another action.
 *
 * Saving a clipped component can be done by clicking the dedicated button.
 *
 * \note When a component is added/deleted, the action needs to be refreshed in order to take the modifications into account.
 * This can easily be done by clicking the update button.
 *
