| =head3  getNodesetStates | ||||
|        returns the nodeset state for the given nodes. The possible nodeset | ||||
|            states are: netboot, install, boot and discover. | ||||
|     Arguments: | ||||
|         nodes  --- a pointer to an array of nodes | ||||
|         states -- a pointer to a hash table. This hash will be filled by this | ||||
|              function. The key is the nodeset status and the value is a pointer | ||||
|              to an array of nodes.  | ||||
|     Returns: | ||||
|        (return code, error message) | ||||
