//KDE adapter is a "data source" adapter for
//Marching cubes alhorithm. It produces scalar
//values in regular grid's nodes, using TKDEFGT class
//to estimate a density.
//IMPORTANT: This class is not intended for end-user's code,
//it's used and _must_ be used only as an argument while
//instantiating mesh builder's class template.
//That's why all members are protected
//or private - end user cannot create object's of this class.
//But mesh builder, derived from this class,
//knows exactly how to use this class correctly.
//SetDimenions and SetE/GetE are public members, it will be derived by mesh
//builder's instantiation and used inside TGL5DPainter class.
