insertNode method

Inserts a node into the Document or DocumentFragment at the start of the Range. If the container is a Text node, this will be split at the start of the Range (as if the Text node's splitText method was performed at the insertion point) and the insertion will occur between the two resulting Text nodes. Adjacent Text nodes will not be automatically merged. If the node to be inserted is a DocumentFragment node, the children will be inserted rather than the DocumentFragment node itself.
