// TinD: Because a UUID is too big for a lot of people
// a TinD is a defaults to a 4 byte ID made up of ONLY Alphabetical characters.
// To ensure more randomness, lower case and upper case letters are used
// providing up to 52 differenct characters for use in each single position.
//
// TinD is at it's core a byte slice. It's default alphabet can be replaced with
// whatever unicode characters you want, as the alphabet it uses is just a slice
// of runes

// defaults are just a call to NewConfig()

// TinD represents a very simple `size` byte unique ID that is generated
// at random. TinD stands for Tiny iDentifier, and is pronouced "tind"
// Each byte can be the value 0 -> len(alphabet) that is used, to ensure
// values can be encoded and decoded reliably. The longer the alphabet
// used, the more randomness can be done.
