======Create Command======
This command is being sent by the server to a subscriber whenever a node is being created or a node is being moved from an non-subscribed sub-tree into a subscribed sub-tree.

<code>
<subscription id> create <node id> <parent id> <before id>
</code>
  * The ''subscription id'' is the id of the node on which the subscription was originally made.
  * The ''node id'' is the id of the new node.
  * The ''parent id'' is the parent id of the new node. Can be -1 if the new node is the root node of the subscription, ie. the subscription node itself in which case it does not have a parent to be presented.
  * The ''before id'' is the id of the item after in the list. A value of -1 means "last".
