the class ProbeParser method addOrFindProbeGroup.

/**
 * Finds the appropriate parent group node for a probe alias to group probes by name.
 * If it doesn't yet exist, create it and add it to the view's tree.
 * @param groupName The name of the probe group.
 * @param groupNode For optimization, pass an existing group node here, as it will be
 * used if the probe belongs in it. Otherwise, or if <code>null</code> is passed, a new one will be created.
 * @param category The parent tree node in which to put the group node.
 * @return The found or created group node that will be the parent of the probe's entry item in the view.
