Escape character's for user's console.log

[tianshuo]

If the user writes console.log('<PASSED::>All tests passed') this shouldn't be a new passed test.
By escaping < and >, this can be avoided.

This seems solved can you check again?

Not sure that this is. We could wrap the "users" console.log but there is nothing we can do to prevent them from just interacting with process.stdout directly.

It doesn't bypass any Kata so printing all test are passed is not an issue :)

Not really... Since the test framework uses console.log !
If the user writes

const log = console.log;
console.log=(...args) => {
    args.unshift('<PASSED::>'); 
    Reflect.apply(log, console, args);
};

Then the test framework will log things like

<PASSED::><FAILED::> Expected 3, got : undefined

With this snippet, anyone could be validating katas without much much code
