One mistake

[YaHoYii]

I found a mistake in the UIBezierPath+WeightedPoint.swift file，https://github.com/uber/UberSignature/blob/master/Sources/Swift/Internal/UIBezierPath%2BWeightedPoint.swift
Original code

 class func line(withWeightedPointA pointA: WeightedPoint, pointB: WeightedPoint) -> UIBezierPath {
        let lines = linesPerpendicularToLine(from: pointA, to: pointB)
        
        let path = UIBezierPath()
        path.move(to: lines.0.startPoint)
        path.addLine(to: lines.1.startPoint)
        path.addLine(to: lines.1.endPoint)
        **path.addLine(to: lines.0. startPoint)**
        path.close()
        
        return path
    }

Sometimes it causes the drawn lines to be jagged.
I read the code of Objects-C，It should be changed to solve this problem.

    class func line(withWeightedPointA pointA: WeightedPoint, pointB: WeightedPoint) -> UIBezierPath {
        let lines = linesPerpendicularToLine(from: pointA, to: pointB)
        
        let path = UIBezierPath()
        path.move(to: lines.0.startPoint)
        path.addLine(to: lines.1.startPoint)
        path.addLine(to: lines.1.endPoint)
        **path.addLine(to: lines.0.endPoint)**
        path.close()
        
        return path
    }

You can confirm this question.
