ap<A, B> function

Applies the function inside a Task to the value inside another Task.

Given a Task containing a function from A to B (fTask) and another Task containing a value of type A (m), this function returns a new Task that will eventually produce a value of type B by applying the function to the value.

Example:

Task<int Function(String)> funcTask = Task(() => Future.value((String s) => s.length));
Task<String> valueTask = Task(() => Future.value("Hello"));
Task<int> resultTask = ap(funcTask)(valueTask);
