A SassScript object representing `#{}` interpolation within a string.
@see Interpolation
Interpolation in a string is of the form `"before #{mid} after"`, where `before` and `after` may include more interpolation.
@param before [Node] The string before the interpolation @param mid [Node] The SassScript within the interpolation @param after [Node] The string after the interpolation

13: @before = before
14: @mid = mid
15: @after = after
16: end
Returns the three components of the interpolation, `before`, `mid`, and `after`.
