  @param {object} oHierarchy The module hierarchy node with selected state
  @param {object} oTree The tree node to be filled with the hierarchy information
  @param {int} iDepth The current depth of the recursion
  @param {boolean} bSelected The selected state of the parent node
  @return {int} The depth of the deepest node in the tree
