Gamma

gamma is a number theory package written in Haskell that aims to provide its users with the following functionality:

A typeclass
```
class Num a => Factorial a
```
that provides a factorial function.
A typeclass
```
class (Eq a, Floating a, Factorial a) => Gamma a
```
that provides the functions
- gamma
- lnGamma (natural logarithm of the gamma function) and
- lnFactorial (natural logarithm of the factorial function).
A typeclass
```
class Gamma a => IncGamma a
```
for the incomplete lower and upper gamma functions.
A typeclass
```
class Gamma a => GenGamma a
```
to represent the multivariate gamma function.
