Merge remote-tracking branch 'upstream/master'
Changed the calculation of the binomial probability to log-scale

In doing so, we can use the native mathematical functions instead of Math::BigInt and Math::BigFloat.
This results in a huge speed up for large input sets. The calculation of the p-values now happens in
less than 1 sec, even for 1000 probes.
