Package stringid provides helper functions for dealing with string identifiers
GenerateRandomID returns a unique id.
IsShortID determines if an arbitrary string *looks like* a short ID.
TruncateID returns a shorthand version of a string identifier for convenience. A collision with other shorthands is very unlikely, but possible. In case of a collision a lookup with TruncIndex.Get() will fail, and the caller will need to use a longer prefix, or the full-length Id.
ValidateID checks whether an ID string is a valid image ID.
