A lenient way to match outputs

[sudo-nan0-RaySK]

Right now, comparison is as simple as :

remarks = expectedOutput === obtainedOutput ? 'Pass' : 'Fail';

It should be more tolerant to outputs where there can be an extra space, a carriage return etc.

Alternatively, best way to do this is by serializing the return value and then compare these serialized objects instead of strings. This has a lot of benefits:

• Data structures can be returned as a result of procedure calls, instead of providing a specific output format for each problem.
• Sometimes people interpret non printable characters in a wrong way (different from intended). This solves that problem so that users never get a penalty just because they counted one space less or more.
