Simplified asMethod names (recommendation)

Suggest removing the `random` prefix to all the asMethods. So class level methods like:
```
Randoms.randomInt(10,20)
Randoms.randomString(ofLength: 16)
Randoms.randomFakeName()
```
become shorter to:
```
Randoms.int(10,20)
Randoms.string(ofLength: 16)
Randoms.fakeName()
```
