[FieldTrip] stat.stat matrix of ft_XXXstatistics

Dear Kavi,

the t-values are not corrected for multiple comparisons. In order to check if a t-value has passed the significance criterion, you can take a look at the .mask-field. Here, each element is coded with either 0 (not significant) or 1 (significant).
