Feat/future date

Resolve: #245

super close! instead of test i use example so that way the doc has a usage example and examples can be used for tests as well. If you want to keep your test thats fine just be sure to add an example.

Unfortunately, I have no idea how to write example here.
Since FutureData depends on current datetime and output string in example should equals what `FutureDate returns.
Otherwise example will fail on running tests.
Maybe do you have any suggestion?

setting a seed should do it. every other function has an example, this should be the same. If your having issues try to setup it up as close as possible like the others and show me the code and ill help you figure out the rest of the way.

I mean FutureDate at first calls time.Now() and then adds random time duration to it.
So every FutureDate result will higher than the previous one.
Due to that I'm not able to write constant string in output example.
I pushed another one commit with example but without output string.
