Developer nodes

The following base classes are useful if writing new nodes:

node.Node(*parents[, dims, plates, name, ...])	Base class for all nodes.
stochastic.Stochastic(*args[, initialize, dims])	Base class for nodes that are stochastic.
expfamily.ExponentialFamily(*args, **kwargs)	A base class for nodes using natural parameterization phi.
deterministic.Deterministic(*args, **kwargs)	Base class for deterministic nodes.

The following nodes are examples of special nodes that remain hidden for the user although they are often implicitly used:

constant.Constant(moments, x, **kwargs)	Node for presenting constant values.
gaussian.GaussianToGaussianGamma(X, **kwargs)	Converter for Gaussian moments to Gaussian-gamma isotropic moments
gaussian.GaussianGammaToGaussianWishart(...)
gaussian.WrapToGaussianGamma(X, alpha[, ndim])
gaussian.WrapToGaussianWishart(X, Lambda[, ndim])	Wraps Gaussian and Wishart nodes into a Gaussian-Wishart node.
