Determining the type of loop. If true - FULLNESS, if false - HOLE

Appends sample points along this curve, numSamples - number of points for the partition of the curve. if numSamples == 0 - partition curve depending on the type and interval

if area > 0 - clockwise(CW), area < 0 - counter-clockwise(CCW).

Determining whether to do a reverse curves in a loop

Determining the extents for profiles

creates arrays of curves that form "CurveLoops
