   - *node*: If you pass a node, the method will return its children. Defaults to "null" (this means it will return ALL nodes).
   - *direct*: If you pass true as a value for this argument, you'll get only the direct children of the node
   - *options*: An array of options that allows you to decorate the results with HTML. Available options:
-    + decorate: boolean (false) - retrieves tree as UL->LI tree
-    + nodeDecorator: Closure (null) - uses $node as argument and returns decorated item as string
-    + rootOpen: string || Closure ('<ul>') - branch start, closure will be given $children as a parameter
-    + rootClose: string ('</ul>') - branch close
-    + childStart: string || Closure ('<li>') - start of node, closure will be given $node as a parameter
-    + childClose: string ('</li>') - close of node
-    + childSort: array || keys allowed: field: field to sort on, dir: direction. 'asc' or 'desc'
