Safe Call

1. Create a function called safeCall that accepts another function f as a parameter, calls f without any arguments and returns true if f has executed without any errors or false if f has thrown an error. Sample usage:

   safeCall(() => console.log('Hello!')); // true
   safeCall(() => JSON.parse('abc')); // false
   safeCall(() => false); // true
   safeCall(() => abc); // false

2. (optional) Make safeCall callable on any function: f.safeCall(...). It should take the same parameters and has the same effect as f.call(...), except in case when f throws an error, it should instead just return null without throwing any errors.
