| DfsuUtilFindTopLayerElements Method (IDfsuFile) | 
            Find element indices (zero-based) of the elements being the upper-most element
            in its column.
            
            Each column is identified by matching node id numbers. For 3D elements the
            last half of the node numbers of the bottom element must match the first half
            of the node numbers in the top element. For 2D vertical elements the order of 
            the node numbers in the bottom element (last half number of nodes) are reversed 
            compared to those in the top element (first half number of nodes).

Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type 
IDfsuFile. When you use instance method syntax to call this method, omit the first parameter. For more information, see 
Extension Methods (Visual Basic) or 
Extension Methods (C# Programming Guide).
Remarks
            To find the number of elements in each column, assuming the result
            is stored in res:
            
            For the first column it is res[0]+1.
            
            For the i'th column, it is res[i]-res[i-1].
