Decode returns a token from a 1-12 character base62 encoded string.

New returns a `Base62` encoded `Token` of *up to* `DefaultTokenLength` if you pass in a `tokenLength` between `MinTokenLength` and `MaxTokenLength` this will return a `Token` of *up to* that length instead if you pass in a `tokenLength` that is out of range it will panic.

Base62 is a string respresentation of every possible base62 character.

DefaultTokenLength is the default size of a token.

ErrInvalidCharacter is the error returned or panic'd when a non `Base62` string is being parsed.

ErrTokenTooBig is the error returned or panic'd when a base62 token is larger than `MaxTokenLength`.

ErrTokenTooSmall is the error returned or panic'd when a base62 token is smaller than `MinTokenLength`.

MaxTokenLength is the largest possible character length of a token.

MinTokenLength is the smallest possible character length of a token.

Error is a token error.

Token is an alias of an uint64 that is marshalled into a base62 encoded token.
