While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
* Extract Binomial Distribution functions from Statistical
Replace the old MS algorithm for CRITBINOM() (which has now been replaced with te BINOM.INV() function) with a brute force approach - I'll look to refine it later. The MS algorithm is no longer documented, and the implementation produced erroneous results anyway
* Exract the NEGBINOMDIST() function as well; still need to add a cumulative flag to support the additional argument for the newer NEGBINOM.DIST() function
* Rationalise validation of probability arguments
