Function compose

compose<A, B>(fn1: ((x: A) => B)): ((x: A) => B)
A generic compose function that takes multiple functions as input and outputs a single function where input = input of the first function and output = output where every funtion has been applied to the output of the previous one.

So
```
compose(f1:(x:A)=>B, f2:(x:B)=>C, f3:(x:C)=>D)
```
will return a single unary function
```
(a:A):D => f3(f2(f1(a)))
```
