def get_handle_from_nodehandle(nodehandle):
'''
<Purpose>
Given a node handle (e.g. 192.168.1.1:1224:v8), figure out its vesselhandle.
<Parameters>
nodehandle:
A string representing a vessel, in the format 'node_id:port:vesselname'
<Exceptions>
NMClientException
<Side Effects>
Connect to the given node handle.
<Return>
The vesselhandle that corresponds with the node handle.
