The help section of the function code should be prepared properly to show the usage (including inputs and outputs) when you type:
It should not be necessary to inspect the code, or the code in a secondary function (i.e ControlCentor.m [sic]).
Secondly, the functionality seems correct but somewhat incomplete.
When I use the example from the Wolfram website, it gives the same result as the website and the other two Fisher test functions on FileExchange (myfisher and Fisherextest). However it only gives one sided p-value, not both tails, which are provided by those other two functions.
