METHOD TO ADJUST A LINEAR CURVE TO A SET OF LINE POINTS.

Parameters

ptpol	is a pointer to a PointList
maxDist	is the maximum distance to the line fitted for a set of points

Returns: FALSE if there is no memory available, the number of points are lower than 2 or maxDist == 0.0; TRUE if the curve is adjusted with no errors
