Function nextRandomGaussian( )

Description:
Returns the next value in a random sequence, sampled from a Gaussian distribution with mean of 0.0 and standard deviation of 1.0.

This function will give a different result every time, hence it is not suitable for use in an expression which should have a fixed value, for instance to define a TOPCAT column.

Parameters:
Return Value (floating point):
random number
Signature:
double nextRandomGaussian()
