Provided is an apparatus comprising a tensioner, first clamp, first slide, second clamp, and second slide. A tensioner may be adapted to apply a tensile force along a first dimension, may comprise a first end and a second end movable with respect to one another, and may be adapted to apply a clamping force therebetween. A first slide may be adapted to secure the first clamp such that the first clamp is substantially free to move in a second dimension and may comprise a first end and a second end movable with respect to one another. A second clamp may be adapted to apply a clamping force between the first end and the second end and may be adapted to secure the second clamp, such that the second clamp is substantially free to move in the second dimension. |
