commit 2c913f1ecae1bcce99f7d1b45a110adc402e2d1b
Author: John Darrington <address@hidden>
Date:   Thu Sep 19 07:16:51 2013 +0200

    Added a test which checks the Fisher Exact Test results

commit f219320996e359b41708a94059e5f27a45926bf6
Author: John Darrington <address@hidden>
Date:   Wed Sep 18 19:16:08 2013 +0200

    Calculate Fisher Exact Test even if all cell counts >= 5
    
    Remove the condition that one of the cell counts must be < 5
    before calculating the fisher exact test.  This condition seems
    to be an anachronism, but still (erroneously) documented in Algorithms.

commit d6ae7d8fcbc2aa7d559f2d15414be4bc9a28befb
Author: John Darrington <address@hidden>
Date:   Wed Sep 18 21:00:34 2013 +0200

    Correct error calculating significance of fisher exact test.
    
    The two tailed significance is the sum of the one tailed signficance and 
those point significances which
    are greater than P(N = n1)

commit 1c14db584d9a90589ae04889975944e4e7ca3a77
Author: John Darrington <address@hidden>
Date:   Wed Sep 18 20:37:59 2013 +0200

    Crosstabs: Use logarithms to calculate the product/quotients of factorials
    
    Avoid overflow of large numbers resulting from factorials, by using the 
logarithms as
    intermediate results
