jpx_metanode::add_regions

Use this function to add a descendant to the present node, assigning this descendant to represent an ROI description box. If this node is assigned its own descendants, it will be represented by an association box, whose first sub-box is the ROI description box; in this, the most useful case, the node's descendants will all be associated with the image regions supplied via the regions array. If no descendants are added to the new node, it will be represented as an isolated ROI description box all by itself.

Reference to the newly created node.
