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:
