	'''This class defines the Lab Environment for the Cluster Test System.
	It defines those things which are expected to change from test
	environment to test environment for the same cluster manager.

	It is where you define the set of nodes that are in your test lab
	what kind of reset mechanism you use, etc.

	- This class is derived from a UserDict because we hold many
	- different parameters of different kinds, and this provides
	- a uniform and extensible interface useful for any kind of
	- communication between the user/administrator/tester and CTS.
	-
	At this point in time, it is the intent of this class to model static
	configuration and/or environmental data about the environment which
	doesn't change as the tests proceed.

	Well-known names (keys) are an important concept in this class.
	The HasMinimalKeys member function knows the minimal set of
	well-known names for the class.

	The following names are standard (well-known) at this time:

	nodes An array of the nodes in the cluster
	reset A ResetMechanism object
	logger An array of objects that log strings...
	CMclass The type of ClusterManager we are running
	(This is a class object, not a class instance)
	RandSeed Random seed. It is a triple of bytes. (optional)

	The CTS code ignores names it doesn't know about/need.
	The individual tests have access to this information, and it is
	perfectly acceptable to provide hints, tweaks, fine-tuning
	directions or other information to the tests through this mechanism.

	-class CtsLab(object):
	- '''This class defines the Lab Environment for the Cluster Test System.
	- It defines those things which are expected to change from test
	- environment to test environment for the same cluster manager.
	-
	- It is where you define the set of nodes that are in your test lab
	- what kind of reset mechanism you use, etc.
	-
	- This class is derived from a UserDict because we hold many
	- different parameters of different kinds, and this provides
	- a uniform and extensible interface useful for any kind of
	- communication between the user/administrator/tester and CTS.
	-
	- At this point in time, it is the intent of this class to model static
	- configuration and/or environmental data about the environment which
	- doesn't change as the tests proceed.
	-
	- Well-known names (keys) are an important concept in this class.
	- The HasMinimalKeys member function knows the minimal set of
	- well-known names for the class.
	-
	- The following names are standard (well-known) at this time:
	-
	- nodes An array of the nodes in the cluster
	- reset A ResetMechanism object
	- logger An array of objects that log strings...
	- CMclass The type of ClusterManager we are running
	- (This is a class object, not a class instance)
	- RandSeed Random seed. It is a triple of bytes. (optional)
	-
	- The CTS code ignores names it doesn't know about/need.
	- The individual tests have access to this information, and it is
	- perfectly acceptable to provide hints, tweaks, fine-tuning
	- directions or other information to the tests through this mechanism.
