Trevor Parscal	713a80596d	Added es.DocumentLeafNode, which like es.DocumentBranchNode is a mixin-like class (we may want to switch to using a more natural composition mechanism than es.extendClass in the future) - now es.DocumentNode also has an abstract method called hasChildren which returns a boolean and can indicate if a node is a leaf or a branch.	2011-11-10 19:26:02 +00:00
