%
% M_NORM_T Performs a test that a normal mean is equal to a specific value.
%	M_NORM_T(M0,PROB,T,DATA) gives a matrix where the first column contains
%	values of the Bayes factor and the second column contains the corresponding
%	posterior probabilities.  M0 is the value to be tested, PROB is the prior
%	probability of the hypothesis, T is a column vector of prior standard deviations
%	of the normal prior under the alternative hypothesis, and DATA is the vector
%	containing the sample mean, the sample size and the population standard 
%	deviation.
