[StarCluster] development shell - unbound method run_plugin() must be called with Cluster instance

[Stuart Young]

Hi All,

Fyi, I figured out I needed ClusterManager (not Cluster). Here's the way 
to access the ClusterManager **instance** (i.e., not the type):

clus = cluster.ClusterManager(cfg)
cluster.ClusterManager.run_plugin(clus, 'automount', 'smallcluster')


Cheers,

Stuart
