Elements.swift:19class Elementsclass Elementsimport SwiftSoupprotocol BidirectionalCollection<Element> : Collection where Self.Indices : BidirectionalCollection, Self.SubSequence : BidirectionalCollectionA collection that supports backward as well as forward traversal.
protocol Collection<Element> : SequenceA sequence whose elements can be traversed multiple times, nondestructively, and accessed by an indexed subscript.

protocol EquatableA type that can be compared for value equality.
protocol Escapableprotocol NSCopyingThe NSCopying protocol declares a method for providing functional copies of an object. The exact meaning of “copy” can vary from class to class, but a copy must be a functionally independent object with values identical to the original at the time the copy was made.
