Calculates the center points and the tangential point of the circles that are tangential to a given curve with a given circlepoint and have the given radius. There may be any number of solutions, including no solution. Each solution consists of two points: 1.: the center, 2.: the tangential point to the curve. The length of the returned array is a multiple of 2 (or 0)
