Input Array: Nx3 Array of Points in [x,y,z form]
1. Thin points from 'points' array
thinned_points, regression_lines = thin_line(points)
2. Sort points
sorted_points = sort_points(thinned_points, regression_lines)
3. Visualize
4. Fine tune:
thin_line: point_cloud_thickness controls the radius in which points are selected to perform principle component analysis for.
sort_points: sorted_point_distance controls the radius adjacent points are selected for ordering the thinned curve.
