Maintain directionality when exporting relationship matrix.

[SewerynRoznowski]

Description

When exporting the relationship matrix to excel, the directionality gets lost.

As seen below, the directionality is checked to see if there is a trace, but the direction is ignored and the cell is always set to "X" if there is a trace.

	for (var j = 1; j < this.Matrix.Records[i - 1].Count; j++)
	{
	var trace = relation[j].RelationshipDirection != RelationshipDirectionKind.None;
	if (trace)
	{
	traceCount++;
	}
	worksheetMatrix.Cell(i + 1, j + 1).Value = trace ? "X" : string.Empty;
	}

As a user it would be great to be able to maintain this directionality, it makes it alot easier to analyse relationships later.
