0013557: field values display

Now you can display values applied to the cells or nodes of 3D presentation intended for visualization of calculation data. New methods are provided in actor.

This functionality is implemented on the base level. Vector actor re-implements  GetValLabelsInput() only in order to provide correct data set for it.
