Binomial Test Incorrect P-Value Two-Tailed

[GoogleCodeExporter]

The Binomial test yields an incorrect P-Value for the Binomial Two-Tailed test 
but is correct for both One Tailed results compared to SciPy and R.

What steps will reproduce the problem?

1. use Constructor: BinomialTest(int successes, int trials, double    
hypothesizedProbability, OneSampleHypothesis alternate);
2. No. of trials 235
3. No. of successes 51
4. HypothesizedProbability 1/6

What is the expected output? What do you see instead?
Two Tailed
Statistic = 51
Accord.Net = 1.96404518910672
R = 0.04375
SciPy= 0.043747970182413443

What version of the product are you using? On what operating system?

v2.8.2

Thanks, will be fixed on next release. Binomial was being assumed symmetric in 
cases where it shouldn't.
