Proposed new feature: hide siblings

[GoogleCodeExporter]

I'd like to suggest some additional functionality: when a node is expanded, the 
siblings of the expanded node are hidden. Closing an expanded node should 
unhide its siblings.

This makes it easier to focus on only the path down to the most-expanded nodes, 
which is particularly helpful when there is a large number of children for some 
(most?) of the nodes. 

The following patch against $Revision 520 works for me(tm), but the
default for autoHide should probably be false:

As of 2014 Dynatree is feature frozen.
Please have a look at Fancytree (sequel of DynaTree 1.x): chances are good that 
the problem was resolved / the requested featuer is already implemented.
Please open a new issue there otherwise:
