API

$3

A node is represented by an object of the following form:

`js
{
id: ,
data: {
[property: ]: >
},
parentId: | null,
children: >
}
`

$3

A node can have a distinguished child. You can specify the distinguished
children of nodes with an object of the following form:

`js
{
[id: ]:
}
`

Every value is the id of the distinguished child of the node with its key as id.
If the currents object doesn't specify a distinguished child for a node, the
default will be the first child index-wise.
