Fixed issues in DivideAndConquerAlgorithm: in one case, the points were shifted such that one point was defined left or right with a value of 10^-17 to a line between two other points. When this point was inserted into the adjacent points around one of the points of this line, the angle found was indicating that this point was actually on the line instead of having a bit offset. Second, the function DocRecord::DListInsert should be modified such that if the difference between alpha en beta is too small or when alpha is almost zero, it should check on being left or right as well.
