======Create New Node======
This command creates a new node in a specified parent. the node id can either be set explicitly or a placeholder variable can be used, which can then in the same command string be used, instead of node id, in commands after the create command.

<code>
create <node id|placeholder> <parent node id> <before id>
</code>

If the ''parent node id'' does not exist an [[cmd:s_error|error]] is returned.

The node will be inserted in the child list of the parent, before the ''before id''. It can be -1, meaning "insert last".

Placeholder example - create new node as child of node 2 and set its title to "Helo", and then "Hello":
<code>
create x 2 -1; update x title "Helo"; update x title "Hello"
</code>

Multiple placeholders example - create two new nodes as children of node 2 and set their titles to "Hello1", and then "Hello2":
<code>
create x 2 -1; create y 2 -1; update x title "Hello1"; update y title "Hello2"
</code>
