DESCRIPTION:
	This module generates a 1-, 2-, or 3-D fields of arbitrary size whose
elements are gaussian-distributed random floating point values.

   Dimension	- This dial selects the dimension of the field.  Be careful
		  when increasing this value if the module is already in a
		  network because other modules may not expect fields of
		  changing dimension.  Also, you can run out of memory very
		  quickly if the Xdim, Ydim, and Zdim are all relatively large
		  values.

   Reseed	- This one-shot button gives a new seed to the random number
		  generator and causes a new field to be generated.

   Mean		- The average value of the random number field.

   Sigma	- The standard deviation of the random number field.

   Xdim, Ydim, Zdim - Size of the field in each dimension.  Only the widgets
		  which are appropriate to the Dimension selected will be
		  visible.
	
EXAMPLE: Using the default settings, this network will display a gaussian field
as a grayscale image and allow the user to verify the mean and standard
deviation of the field.
