Detailed Description

1. Without using texture.
   In this case colors of nodes are specified with DataMapOfIntegerColor and presentation
   is built with gradient fill between these nodes (default behaviour)
   
2. Using texture.
   In this case presentation is built with spectrum filling between nodes. For example, if
   one node has blue color and second one has violet color, parameters of this class may be
   set to fill presentation between nodes with solar spectrum.
   Methods:
   UseTexture - activates/deactivates this way
   SetColorMap - sets colors used for generation of texture
   SetColorindices - specifies correspondence between node IDs and indices of colors from color map
