ThrowingFunction (Maybe - Safely handle exceptions)

Type Parameters:

T - the type of argument passed to the function

R - the type of results returned by the function

E - the type of exception that the function throws

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface ThrowingFunction<T,R,E extends java.lang.Throwable>
```
The same as Function, but the lambda expression throws an E checked exception.
This is a functional interface whose functional method is apply(Object)

Since:

v0.1.0
