	Name		Type	Default	Choices
	Variance	typein_real	32.00	 0.00	 0.00

DESCRIPTION
	This module generates an n-dimensional Gaussian field.  The data
	value at each point is given by the following:

		    2
		  -r
		  ---
		  2*v
		e     ,

	where r is the Euclidean distance of the point from the centre of the
	field, and v is the variance.

PARAMETERS
	Variance (typein_real)
		The variance of the Gaussian function.

	Num Dimensions (typein_integer)
		The number of dimensions of the output field.

	Dimension n (typein_integer)
		The length of the nth dimension.

OUTPUTS
	output - field 1-vector uniform float
		The field representing the Gaussian function.

	This example nextwork constructs a Gaussian field and passes it through
	the orthogonal slicer for visualization.
