    Return the closest point to the given point, for example the nearest point to the mouse. Return the most near point at any distance: > distances.closest(mouse.position) point Return the most near point, also within 100px radius distance: > distances.closest(mouse.position, 100) Of which is the same as: // within 100px of the mouse position > distances.within(100, mouse.position)

      Return the closest point to the given point, for example the nearest point to the mouse.

          Return the most near point at any distance:

        > distances.closest(mouse.position)
        point

    Return the most near point, also within 100px radius distance:

        > distances.closest(mouse.position, 100)

    Of which is the same as:

        // within 100px of the mouse position
        > distances.within(100, mouse.position)

      intersect

      (
      point , padding
      )
      from class_name
      dict_keys(['kind', 'word', 'static', 'computed', 'is_symbol', 'value', 'type', 'comments', 'pos']) 
          Check if a point _intersects_ another point, returning the interecting
    top point.

        > intersect(mouse)
        point  // a point under the mouse.

    To _pad_ the overlap distance, provide an addition padding value:

        > intersect(mouse, 10) // add 10px around the perimeter
        point

    Useful if the intersection point has a radius:

        > intersect(mouse, mouse.radius) // add 10px around the perimeter

    This is the same as calling `closest()`, with the second arg as a function
    for radius testing.

      within

      (
      maxDistance , point
      )
      from class_name
      dict_keys(['kind', 'word', 'static', 'computed', 'is_symbol', 'value', 'type', 'comments', 'pos'])

      Return a point within the max distance set

          // return the closest point within 100px (radius) from the mouse position
    > distances.within(100, this.mouse.position)
    point

For a _list_ of points, use `near`.

    near(point, distance=point.radius)
    [point, ...]

      Each distance is tested against the curent low. If the distance v is less than low, store p.

          In the first iteration, `setterFunc`, does not do a test, and replaces
    _itself_, with a testing function.

    This ensures we don't need to check for the first `undefined` .
