Coding Challenge: An AI which matches text with nlp!

As suggested by @ShreerangV in https://github.com/CodingTrain/website/issues/564:

See this:
``` javascript
var s = 'I need to use a tissue'
```

Now what you should do:
``` javascript
var t = 'I want a tissue';
console.log(s.test(t));
// Should return true
t = 'Tissue please!';
console.log(s.test(t));
// Should return true again!
t = 'Can I have a tissue?';
// etc.
```
