• Expose tree type (GRUPTREE/BRANPROP) to frontend
• Improvements to tree filtering:
  • Include only dates where the current tree type is defined
  • include only WELSPECS nodes that belongs to the current tree (WELSPECS nodes can in theory belong to both trees, one of the trees or none of the trees). This can be done by filtering on that the parent node exists in the GRUPTREE/BRANPROP rows.

We must assume that if the tree is redefined, then the whole tree is redefined. Eclipse might not demand this.
