Returning an error

[herkyl]

First of all really good job creating this library! Coming from Node.js I was searching for a shortid alternative a year ago, you finally created it!

When can I expect this library to return an error?
Could this happen randomly, should I panic at this point? Or will this only happen during the first Generate() call?

I'm asking because my current ID generation module does not return an error and I'd prefer to keep my code this way.

Generally, it should not return any errors as the only source are alphabet-based encoding and those are mostly hypothetical rather than real.
