Add non-flat-selection mode

Issue #168 & #145

When all children of a node are checked only the parent node is returned in the selection, this is required in some use cases.

I cloned the code, made the change, tested it, applied to demo project, I kept the current behavior as default and added a boolean to config to control it (flatSelection).
