"each parent node in the tree is a SimSet or SimGroup and each leaf node is a SimObject.\n\n"
"Each item in the tree has a text and a value. For trees that display SimObject hierarchies, the text for each item "
"is automatically derived from objects while the value for each item is the ID of the respective SimObject. For trees "

"present on a tree, is 0.\n\n"
